Research challenges the materialistic understanding of death, according to which biological death represents the final end of existence and of all conscious activity.

We are not just highly evolved animals with biological computers embedded inside our skulls; we are also fields of consciousness without limits, transcending time, space, matter, and linear causality.

I believe that used responsibly and in a mature way, the entheogens mediate access to the numinous dimensions of existence, have a great healing and transformative potential, and represent a very important tool for spiritual development.

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

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.

There is an urgent need for a radical revision of our current concepts of the nature of consciousness and its relationship to matter and the brain.

According to materialistic science, any memory requires a material substrate, such as the neuronal network in the brain or the DNA molecules of the genes.
