Here's what a friend has to say on the subject...

"I've told this real story before. A native American [Cheyenne/Arapaho] I knew well in New Mexico told me that when he was 21 in the late 1960s he wanted to experience the vision quest of his ancestors. It was a time when many young Indians were re-exploring their roots. His grandmother initiated him into the way of it. On her directions he fasted several days and went to a sacred mountain area in S Dakota near the reservation with only a blanket, made a cirle of stones and sat inside it, day and night for several days. He had incredible experiences---a few were visitations and audible "words" from both spiritual animals and real ones, a sense of virtual soul travel or OBE and interactions with "ancestors." He recited these upon entering his grandmother's house, standing there proudly with his robe and walking staff in hand. Grandmother listened patiently while she washed the dishes, turned around when he was finished and said: "A man who has many visions has a weak spirit." It was a kind way of saying he was "psychotic," not centered. A true visionary on a quest comes back centered on a clear path of what to do with his life and reenters society humbly to do it well. Chop wood, carry water after enlightenment says the old zen aphorism."
