I have taken part in ceremonies with North American and Mexican shamans, as well as Brazilian ceremonies.

It is possible to transcend the usual limitations of the body, ego, space, and linear time.

The knowledge of the realm of death makes it possible for the shaman to move freely back and forth and mediate these journeys for other people.

The problems that stand in the way are not of economical or technological nature. The deepest sources of the global crisis lie inside the human personality and reflect the level of consciousness evolution of our species.

For any culture which is primarily concerned with meaning, the study of death - the only certainty that life holds for us - must be central, for an understanding of death is the key to liberation in life.

We have to recognize that spirituality is a legitimate dimension in the psyche. It's a legitimate dimension in the universal scheme of things. It doesn't mean that you are superstitious, that you are in to magical, primitive thinking, if you take spirituality seriously.

Consciousness after death demonstrates the possibility of consciousness operating independently of the body.
