From "Common Themes in South American Indian Yagé Experiences", by Michael Harner (in Hallucinogens and Shamanism, ed. Michael J. Harner, 1973):
Of the group yagé session of the Desana branch of the Tukano Indians in eastern Colombia, Reichel-Dolmatoff (1971:173) reports:
The hallucination has several phases, and during the first the person feels and hears a violent current of air, as if a strong wind were pulling him along; the kumu [ritual leader] explains that it is the ascent to the Milky Way; in order to arrive at their final destination, they must leave this world and first find the current of communication with the winds. Now, following the Milky Way, the men descend to Ahpikondia [Paradise]. (my emphasis)
Came across this account by Sven Johansen at the BBC, on a radio program devoted to Mystical Experiences (http://www.bbc.co.uk/iplayer/episode/b01...).
In 1986, I was sitting alone one evening, listening to very beautiful music. Suddenly it was as if the air changed temperature, and as if a breeze blew through the room which was closed - and I knew, immediately, I was in the presence of something more sacred and more beautiful and more vast than I had ever known. Around me was a very bright light and the next two hours I had implanted in my mind an understanding - almost as if it was plugged in, in an instant - it gave me an understanding of the purpose of life, and an understanding of my purpose in life. The overall message was: "Don't worry, it is all happening according to plan".
