Dalai Lama Discusses Quantum Effects with Chinese Scientists

Dialogue with Chinese Scientists about Quantum Effects - First Day

Thekchen Chöling, Dharamsala, India - The first discussions between Chinese, mostly Taiwanese, scientists and His Holiness the Dalai Lama took place in the Tsuglagkhang, the Main Tibetan Temple adjacent to his residence today. His Holiness walked to the temple, greeting members of the public who were waiting to see him in the yard. Once he reached the temple he acknowledged the assembled monks and paid his respects before the statue of the Buddha. After warmly greeting the nine Chinese presenters, he made a point of reaching out to old friends among the assembled guests. He then joined the presenters seated around a long table.

Among the monks at the head of the temple were six Tibetan presenters, graduates of the Emory Science program, who will participate in discussions with the Chinese scientists in the afternoons. Approximately fifty guests sat in the back of the temple, including many who came with the Taiwanese group. About 270 Tibetans joined the audience: researchers from His Holiness’s office, as well as students from the Men-tsee-khang, the College for Higher Tibetan Studies, Sarah, the Tibetan Children’s Village and neighbouring schools. The meeting was conducted in English with simultaneous translation into Chinese and Tibetan being made available over FM radio. Proceedings were web-cast live.

His Holiness opened the conversation. “Firstly, I would like to welcome all of you here. This is the first time we’ve held discussions with mainly Chinese scientists. I’ve taken part in dialogues with scientists for more than 30 years, but they have mostly involved Western scientists, Americans and Europeans, as well as one or two meetings with Japanese and Indians.

“These meetings have two purposes. The first is to expand our knowledge. Until the late 20th century the focus of scientific research was mostly on external things. There was little interest in the mind, only investigations of the brain. The discovery of neuroplasticity, the recognition that changes can be seen in the brains of people who, for example, develop firm concentration, changed that way of thinking. Some scientists are now showing greater interest in the mind, even subtle consciousness.

“There are cases of people who are declared clinically dead—their hearts have stopped, circulation has ceased and their brains are dead—and yet their bodies remain fresh. This was the case with my own teacher, who remained in this state for 13 days. Others remain for anything up to two or three weeks. This is a something to investigate. In the Buddhist tradition we have an explanation that concerns subtle consciousness remaining in the body during this period, but scientists haven’t been able to explain it yet.

“So, one purpose of these meetings is to expand our knowledge, to include the mind as well as external phenomena, in order to achieve a fuller understanding. The second purpose of such discussions concerns the use to which knowledge is put. Despite the useful progress that has resulted from scientific research and technological advancement, there have also been destructive developments that provoke fear. Clear examples are nuclear and other weapons of mass destruction. Their development may have been a remarkable achievement, but their only purpose is to kill.

“Scientists have discovered that constant fear and anger are damaging to our health. They undermine our immune system. On the other hand, cultivating a more compassionate attitude brings peace of mind that reinforces our overall good health. Here’s a simple example: most people prefer a smile to a frown. It’s human nature. Even dogs respond with wagging tails to a smile and other shows of affection.

“Our major religious traditions convey a common message of love, forgiveness and tolerance, but today religious influence is declining. Consequently, in our education programs, in addition to advice about physical hygiene and its benefits for physical health, we need to teach about emotional hygiene—how to tackle our destructive emotions. It should be our aim to be both physically and mentally fit. Promoting inner values on the basis of religious belief has only a limited effect today. However, people are more responsive to evidence based on scientific research.”

His Holiness explained that all 7 billion human beings share a common experience—their mothers give birth to them and nurture them with affection. Consequently, young children care little about differences of nationality, religion or race; they play happily with others who respond with a smile. He observed that as we grow up our education is oriented towards materialistic goals with little time for inner values. He recommended that education should include advice on how to achieve peace of mind.

His Holiness mentioned that he had found his own Buddhist practice useful, but declared that he is no more able to say this or that religious tradition is the best, than he could say that this or that medicine is best in all cases. Just as the effectiveness of medicine depends on the need and condition of the patient, so different religious traditions with the different approaches are suitable for different people according to their disposition, culture and so forth. He suggested that at the present time ethics can be most effectively presented from a secular point of view on the basis of scientific findings. Looking over to Susan Bauer-Wu and Amy Cohen Varela, His Holiness praised the contributions the Mind & Life Institute has made in this direction.

“A few months ago I was teaching a group of Taiwanese Buddhists when a quantum physicist among them introduced himself to me. This meeting was convened as a result of our conversation. I’m very happy to be meeting with you, Chinese scientists, including this Nobel Laureate, Prof Yuan Tseh Lee.”

His Holiness mentioned that he sometimes feels a reluctance to discuss quantum physics with Westerners whose cultural background is based on Judeo-Christian in case it leads to a conflict of faith. He feels less difficulty in relation to Asians, particularly Chinese. He recalled that when the Chinese Buddhist monk Xuanzang came to India in the 7th century he studied at Nalanda University. He is reputed to have met Nagabodhi a direct disciple of Nagarjuna. Evidently, Chinese Buddhists are familiar with the name Nagarjuna and the Nalanda Tradition.

Noting that relations between Chinese and Tibetans are thousands of years old, he conceded that they have sometimes quarrelled. At other times, such as in the 7th century, their ruling families have intermarried. Since 1974, it was decided not to seek independence for Tibet, provided Tibetans were granted all the rights they are entitled to under the Chinese constitution, including the preservation of their language and culture, as well as the protection of Tibet’s environment. His Holiness remarked that Tibetans can benefit from Chinese help in terms of material development, while Tibetans can share their knowledge of the Nalanda Tradition with Chinese Buddhists.

On behalf of the group of presenters Prof Yuan Tseh Lee thanked His Holiness for inviting them. He described science as a language to communicate with nature, a language that we need to learn. Science is based on evidence. He added that since human population and consumption of resources are growing, causing us to recognise that we live in a finite system, science also has a social responsibility. He told His Holiness they would like to hear from him how science, religion, humanity and nature should interact. His Holiness replied that when he first expressed interest in science, an American Buddhist friend warned that science is a killer of religion. He considered this and decided that since science is a method for coming to terms with reality, it is not a threat to the Buddha’s teachings.

Dr Shih Chang Lee opened the scientific presentations with an explanation of space-time symmetry and quantum physics. He talked about Newton’s law of inertia and Einstein’s observation that massless particles move with the velocity of light, leading to his conclusion that velocity is relative, which is described as special relativity.

Dr Chii Dong Chen opened his account of the entangled world by asking what we learn from nature and showing a video clip that compared the activities of foraging ants with a robot vacuum cleaner. He went on to discuss how birds navigate with particular reference to the Bar-tailed Godwit that flies across the Pacific Ocean to breed. He suggested that unique features of quantum mechanics, superimposition and entanglement, can help us understand birds use of magnetoreception. He introduced the contrast between a conventional computer that calculates serially and a quantum computer that can conduct a series of calculations simultaneously.

Dr Chen’s pointing out that things look different from different angles prompted His Holiness to observe that from a Madhyamaka standpoint there is a difference between our perception of the world and its reality. He mentioned the quantum physicist from China who told him that in his experience some of his colleagues with deep understanding of quantum physics were less subject to emotional disturbance. He also recalled American founder of cognitive therapy, Aaron Beck’s description of an angry peoples’ sense that the object of their rage is completely negative as 90% mental projection. Dr Chen agreed that the observer is important because he or she is part of the perception.

Dr Yueh-Nan Chen’s presentation was entitled ‘From Quantum Physics to Quantum Biology’. He discussed Schrodinger’s cat and jokingly reported that when he tried to explain it to his wife she asked why he wanted to kill a cat when to do so would be completely against Buddhist precepts. Everyone laughed. He also discussed the Leggett-Garg inequality which defies our intuition on macrorealism.

Finally, Dr Shawn Y Lin described a modern photonic revolution. He observed that sunlight is the engine of life on earth. Max Planck postulated that light was only emitted in quantized form, an insight that has contributed to powerful lasers, LEDs and solar panels. He described ongoing research to improve solar panels to maximize their absorption and predicted that the next generation will be super thin, super absorptive and super effective. Nano-technology will allow for a film that is 98% absorptive of sunlight and only 10 microns thick.

Invited to offer concluding remarks His Holiness described what he had heard as really wonderful, praising the depth of research. “However, we also need further research into how to reduce anger. At present in the world the role of anger seems to be stronger than that of compassion. In day to day life our emotions cause us trouble. We are at peace here, but elsewhere in the world human beings are being killed or dying of starvation—some of them innocent children. So, in addition to physical discoveries we need to consider how to build a happier humanity.”

Concluding the morning’s discussions Prof Yuan Tseh Lee remarked that teachers encourage creativity and innovation, but such qualities derive from simple curiosity.

His Holiness left the temple to return to his residence, interacting with people who lined the way. Lunch was offered to everyone attending the proceedings in the temple yard. In the afternoon, there were discussions between Tibetan monastics who have received scientific training and the visiting scientists. The dialogue will resume tomorrow morning.

Dalai Lama on Understanding the World

Dialogue between Russian and Buddhist Scholars - Understanding the World

Thekchen Chöling, Dharamsala, HP, India - This morning, under stormy skies, His Holiness the Dalai Lama walked from his residence to the Tsuglagkhang, to take part in a second Dialogue between Russian and Buddhist Scholars - Understanding the World. The event was organized by the Center of Tibetan Culture and Information (Moscow), Save Tibet Foundation (Moscow), and the Dalai Lama Trust, with the support of the Center for Consciousness Studies at the Lomonosov Moscow State University and the Institute of Philosophy, Russian Academy of Sciences.

In the temple, he paid his respects before the statue of Buddha Shakyamuni and saluted the monks sitting nearby. He then turned to greet old friends among the nine Russian scientists gathered round a table in the main body of the temple. The remaining space was filled by about 150 observers including 75 Russians, 18 Tibetan monks who have experience of studying science, 17 students from the Institute of Buddhist Dialectics, Sarah, 25 from the Men-tsee-khang, 50 students from the Tibetan Children’s Village, three from Tong-len and two teachers from the Dharamsala Government College, in addition to 18 guests of the Ganden Phodrang.

Telo Rinpoche, Representative of His Holiness the Dalai Lama at the Office of Tibet in Moscow, briefly introduced this second Dialogue between Russian and Buddhist Scholars in Dharamsala. He welcomed the Russian scientists, as well as people viewing the webcast online, noting that proceedings were being made available in English, Russian, Chinese and Tibetan.

Moderator Prof Konstantin Anokhin thanked His Holiness for taking part in the meeting. He informed him that all the participants had read and been impressed by his book ‘Universe in a Single Atom’ and they intended to found this dialogue on ideas taken from it. He asked if His Holiness had any remarks to open with.

“Brothers and sisters, that’s what I believe we 7 billion human beings are,” His Holiness began. “A lot of the problems we face today are of our own making. And yet scientists say that our basic human nature is essentially compassionate. We create problems because we are under the sway of emotions and because we view other people in terms of ‘us’ and ‘them’. Out of short-sightedness we forget that we are all part of humanity, which leads to our doing others harm. We consider that the destruction of our foes is our victory, and in the past that may have been true. But, today, we are so interdependent that when others are harmed, we’re harmed as well, besides which we have to deal with problems like climate change that affect us all.

“What’s more, at this very moment, people are being killed elsewhere in places like Syria and Yemen, while others are dying of starvation. And worst of all there are people killing each other in the name of religion. We contradict our compassionate nature out of a short-sighted failure to recognise the oneness of 7 billion human beings.

“As social animals we depend on our community so the time has come to educate people about our all being the same in being human. Our future depends on each other. Being too self-centred is to be unrealistic. Narrow minded self-interest is uneducated thinking.

“For thousands of years religious traditions have conveyed a message of love for all human beings, but with limited effect. Now, modern education is oriented towards materialistic goals instead. And yet it is our common experience to have been born and cared for by our mothers, consequently young children reveal a fresh, compassionate nature.

“Scientists warn that constant fear and anger are bad for our health, while being compassionate and warm-hearted contributes to our physical and mental well-being. Therefore, just as we observe physical hygiene to stay well, we need to cultivate a kind of emotional hygiene too.”

His Holiness mentioned that he has been engaged in dialogue with scientists focused on cosmology, neurobiology, physics and psychology for more than 30 years. He noted that these are fields modern science and Buddhist science have in common. For example, there is a general agreement about the arising, abiding and destruction of galaxies and the possibility of there having been more than one ‘big bang’ in the past.

As far as physics is concerned, His Holiness reported that nuclear physicist Raja Ramana had told him that quantum physics was new to science, but corresponding concepts can be found in the writings of the Buddhist master Nagarjuna. In terms of psychology, there is a need for more education about how to tackle our emotions. His Holiness remarked that we need to learn how destructive anger and a general lack of concern for others can be. Weapons and the use of force solve no problems, he added, confirming that violence just leads to counter violence, and so it goes on.

He advised that a peaceful mind is good for our health and that our goal should be to avoid violence and make this a century of dialogue. He observed that while not everyone accepts religion any more, scientific findings have a more universal appeal. Therefore, one of the purposes of meetings like this is to discuss how to educate people from a secular point of view of the need to cultivate warm-heartedness.

“In this context,” His Holiness said, “Russia has a particular role between the cultures of East and West. When I was young, there were Russian scholars, Buryats, Kalmyks and Tuvans, in our monasteries, so we already have a connection. Also, during the time of the 13th Dalai Lama, there was some contact with the Tsar.  Accordingly, I’m very happy to have this opportunity to meet and hold discussions with you scholars from Russia.”

Neurobiologist Prof Pavel Balaban opened the conversation, telling His Holiness that he studies the brain, especially the function of the emotions. He remarked that while rats can be shown to have pleasure centres in their brains that can be stimulated revealing an emotional response, he is also interested to see if apparently uncommunicative snails also have emotions.

His Holiness was prompted to repeat a question he often puts to scientists. He explained how sometimes, when he is confident there is no malaria present, he allows a mosquito to drink his blood. However, once it is full it flies off with no sign of appreciation. So, his question is how big does a brain have to be before it’s capable of showing appreciation? Balaban reported that his investigation of rats showed that they are like other species among which 30-40% reveal a natural sense of compassion. His Holiness responded that mammals do seem to respond this way, but it would be interesting to observe reptiles like turtles that hatch from eggs with no direct relationship to a mother and no immediate need for compassion to survive.

His Holiness recommended that as human beings we need to assess whether anger has any value---noting that it destroys our peace of mind. Compassion, on the other hand, brings optimism and hope. He remarked that some religious traditions rely on fear to bring about better behaviour. He rejects this because it tends instead to lead to pessimism and discouragement.

His Holiness introduced two questions related to the mind. Regarding the first he asked if a perfect sperm meets a perfect ovum in a perfect womb, will life begin? And if not, what is the third factor? Secondly, he mentioned a phenomenon observed among some accomplished meditators when they die. Although clinical death has taken place, the body remains fresh for some days because, it is said, the subtlest consciousness still remains. So far, scientists have no answer as to what’s going on.

Until late in the 20th century scientists took interest in the brain, but not the mind, he said. However, more recently they have acknowledged that neuroplasticity can be observed as a result of mental training. Consequently the relationship between the brain and the mind is beginning to be investigated. Buddhist science describes different levels of mind, ordinary sensory consciousness, awareness in the dream state that is subtler, in deep sleep that is subtler still and the consciousness that manifests at the time of death that is subtlest of all. His Holiness indicated that this mind has neither beginning nor end.

Prof Svyatoslav Medvedev told His Holiness that he has examined the nature of the relation between mind and brain in connection with his research into how the brain maintains attention. He remarked that there are things like the laws of thermodynamics that can be demonstrated mathematically but are not easily proved by experiment. He favours taking a more logical approach to some questions. He noted that Pavlov had referred to bright spots on the brain, but it is only now, a century later, that it has been possible to demonstrate what he was talking about.

“We are now moving from pure theory to actual practice,” Medvedev asserted. “We are trying to understand the brain. It may be that consciousness exists separately and that the brain is a kind of interface.”

Summarizing the three instances of the Buddha’s teachings known as the turnings of the wheel of dharma, His Holiness explained that in the first he taught the four noble truths. In the second he elaborated on the third of those truths, the cessation of suffering in relation to overcoming ignorance. Ignorance is defeated by knowledge—in this case an understanding of the reality that things are empty of intrinsic existence. That does not imply nothingness but that things only exist by way of designation. His Holiness clarified that for those who found this explanation too difficult to deal with, the Buddha gave a third group of teachings that took a different approach in discussing consciousness and how the subtlest consciousness can be thought of as Buddha nature.

He further touched on three objects of knowledge—things that are obvious to us, things that are slightly obscure but can be understood through reason and inference, and things that are obscure and can only be understood by relying on others’ testimony. In addition he mentioned the four principles of reason—nature, dependence, function and evidence.

Following a short break for tea, Prof Nikolai Yankovsky, a leading Russian expert on genetics explained that genes can affect whether you are inclined to meditate or benefit from psychological therapy. Similarly, genes can affect susceptibility to anger. His Holiness wondered whether the role of genes may be comparable to the role of subtle energy that goes together with the mind described in the tantras.

Yankovsky said that editing gene code is expected to contribute to remedies for certain kinds of illness. He also remarked that genetic manipulation could be used in the form of a weapon, which raises the question of morality. He pointed out that when scientists make a new discovery morality is not necessarily an issue, but once they try to use it in practice, the question of ethics arises. His Holiness responded that since all sentient beings seek happiness, what brings about benefit and happiness is regarded as good, whereas what causes suffering is regarded as bad.

He also made clear that since anger is part of the mind, its antidote has to be applied within the mind. He observed that scientists have confirmed to him that rocks and the brain consist of the same kind of particles at a subtle level. At a certain point the arrangement of matter in the brain is such that it becomes a basis for consciousness. Then life, a being with feelings of pleasure and pain occurs. He encouraged the scientists to take this up with younger scholars whose brains are fresher in the afternoon.

Prof Evgeny Rogaev described his research into the brain, looking at what genes give rise to schizophrenia. He stated that genetic research confirms His Holiness’s assertion that we are all brothers and sisters and that we do not have to go very far back to find that we all have ancestors in common. He spoke of work that is being done to create models for transforming aggressive into peaceful behaviour involving taming Siberian wild foxes.

Prof Alexander Kaplan told His Holiness of the interest his students in Moscow are taking in this meeting. He mentioned his attempts to make direct contact with the brain in work with stroke victims who have lost the ability to speak or move. He described how their choice of letters displayed on a screen can be gleaned from responses in their brains that enable communication to take place. He sees this as having potential for understanding the workings of emotions in otherwise healthy people.

His Holiness commented that the innermost subtle consciousness that is described as Buddha-nature has immense potential and people are trying to explore it, but it will take a great deal of time.

He concluded the session by thanking everyone for coming and assuring them he would see them again tomorrow. He left the temple and returned to his residence. Participants in and observers of the meeting then enjoyed lunch served in the temple yard and gathered for another session of discussions in the afternoon.
