According to Wikipedia the definition of Tulpas is the following:
निर्मित nirmita[1] and निर्माण nirmāṇa;[2] "to build" or "to construct") also translated as "magical emanation",[3] "conjured thing" [4] and "phantom" [5] is a concept in mysticism of a being or object which is created through sheer spiritual or mental discipline alone. It is defined in Indian Buddhist texts as any unreal, illusory or mind created apparition.
According to Alexandra David-Néel, tulpas are "magic formations generated by a powerful concentration of thought." It is a materialized thought that has taken physical form and is usually regarded as synonymous to a thoughtform.[6]
The tulpa phenomenon is vindicated through the Consciousness-only Doctrine first propounded within the Yogacara School and is part of the Mahayoga discipline of the 'Generation Stage' (Wylie:kye rim; Sanskrit:utpatti-krama) , Anuyoga discipline of the 'Completion Stage' (Wylie:dzog rim; Sanskrit:saṃpanna-krama) and the Atiyoga perfection of effortless 'unification of the Generation and Completion stages' (Wylie: bskyed rdzogs zung 'jug). read more: http://www.absoluteastronomy.com/topics.
Consider how some people attempt to make what can only be imagined feel real. They do this by trying to create thought-forms, or imagined creatures, called tulpas. Their human creators are trying to imagine so vividly that the tulpas start to seem as if they can speak and act on their own. The term entered Western literature in 1929, through the explorer Alexandra David-Néel’s “Magic and Mystery in Tibet.” She wrote that Tibetan monks created tulpas as a spiritual discipline during intense meditation. The Internet has been a boon for tulpa practice, with dozens of sites with instructions. This is so very scary to me. People do not realize how very dangerous this is. I'll touch on her experience more in a bit.
Example: "One case of a particularly nasty thought-form involves satanist Aleister Crowley. He was feuding with “MacGregor” Mathers, one of the founders of the Order of the Golden Dawn. Their gripes with one another are somewhat convoluted and not that interesting nearly a century later. Basically, they were two alpha dogs who both wanted the same bone: to be leader of the Golden Dawn. Their battle went on for years and was chronicled by reporters around the world, or so some claim.
Mathers allegedly started the war when he launched some sort of psychic attack against Crowley which killed all of his bloodhounds and drove one of his servants mad to the point that he tried to kill Mrs. Crowley du jour and had to be restrained. Crowley responded by sending Beelzebub and his 49 demons after Mathers. I'm pretty sure Mathers went mad. He retaliated by sending a thought-form vampire demon that it took him six months to create after Crowley. This creature purportedly rose up from out of Mathers’ solar plexus."
The following is some more information and background on this subject:
"Alexandra David Neel was a French spiritualist and world explorer who had a special love for the Far East. In 1924, as she was traveling through Tibet, she discovered a sect of Tibetan Buddhist monks that had some pretty esoteric beliefs and practiced mysticism.
After spending some time with the Tibetan Buddhists she discovered that the monks were able to construct a being through sheer will power and discipline. They were able to give this being life, and this being did their bidding. The being was a Tulpa, and Alexandra David Neel just had to have one. Even if it led to some very bad things.
Legend says that Neel did in fact create one of these beings. People who came into contact with Neel reported an attractive young monk in her presence that seemed to be a servant of some kind. As time went on, the attractive young monk turned into an overweight, foul-mouthed pervert that tried to make Neel’s life miserable. Neel fortunately was able to will the being away.
In Western occultism a Tulpa is called a thoughtform and can be used to do both good and bad. A thoughtform is created much in the same way as a Tulpa, through will power and a whole lot of magic. I believe that I may have dealt with one of these thoughtforms early in my time as an investigator. I feel that this being was created through black magic and placed as a curse upon the person that needed help. This being appeared as a giant black shadow and made this poor girl’s life hell. I witnessed this huge shadow being and was even shoved by it. Regrettably, I was unable to help this girl. "
Jesus Christ is the answer. Through him nothing can harm you. A personal relationship with him is so important. It keeps us safe and we receive his favor in all we do in life. If you reach out to him, he will listen. He loves us ALL so very much.
