Bardo yoga

[2]According to Gyalwa Wensapa, one should practice tummo before death to experience radiance and then arise as Buddha Vajradhara in one's bardo body.

When the fire element dissolves, body heat disappears and the extremities shake and twitch.

Then comes the phase of rising, in which one sees a more intense light, which is like a sunrise, while one's consciousness flickers like fireflies.

Then during the phase of arrival, one finds oneself in dense darkness and one's consciousness is weak like the light of a single flame.

Then, the phase of arrival dissolves into the radiance (’od gsal) of emptiness, dharmakaya, which is found in all beings.

They are able to go anywhere and is unobstructed by physical things, but when they attempt to talk to people, they cannot hear the dead person.

If the dead person is a yogi, they may be able to recognize that this body is illusory and they may instead take up the form of their chosen meditation deity.

However, the deceased person can prevent this process by staying calm and entering meditative absorption when they have the vision.

One must have the ability to stabilize one's mind on an understanding of emptiness and the yogic means for inducing the four blisses to succeed.

But these methods are inferior to the tantric practice of clear light yoga and lead to weak realizations.
