Bardo Yoga :
This form of Tibetan yoga is based on phenomenon of death in imagination (but being imagination it can not be phenonmenon, the word is used wrongly here). Yogi imagines first that the form of body (standing) dissolves, then organ of sight dissolves and one can not see, then mirror wisdom dissolves and mind becomes very dim and dull, then water element dissolves and secretions of body stop, then organs of hearing and taste and the fire element dissolve, then wisdom of activity dissolves and one can neither act nor will and finally conciousness dissolves and yogi as dying person experiences four lights of void and unconscious also dissolves into light and light of death-the innate light emerges and all delusory manifestations of Bardo (Death) will appear. The yogi attains weird powers as to travel anywhere without obstruction, to become invisible, is clairvoyant and telepathic. The maximum period of bardo life (this yoga practice) is 7 days and can be repeated 7 times i.e. for total 49 days. The caution prescribed is that only a yogi in advance stage should practice it and should not ignore the instructions. This form of Tibetan yoga is also a weird fantasy.

Transformation Yoga :
This form of yoga is devised to deliver one's consciousness to Buddha's pureland or higher realm of birth. The practioner visualizes himself as body of patron Buddha itself. Yogi also imagines Buddha sitting in the sky and five coloured light radiating at heart centre. He then gently mutters "Gha" seven times. In four days he will experience itch at the top of head and in this centre a lump will arise and secret yellowish liquid which is sign of accomplishment.
Tiben yoga forms are more fantasies, illusions, confusions and tantric rather than Buddhist. Buddhism aims at real enlightenment. None of these conform to scientific scrutiny. In scientific terms these are "Cont and Syndromes" and "Tunnel Visions" and are mental aberrations and can be induced artificially by stimulating respective parts of brain by electric stimulation.
