Mystical-type experiences are profound and often characterized by an authoritative sense of the unity and sacredness and sometimes interpreted as an encounter with God or Ultimate Reality.

Psilocybin in the form the Psilocybe genus of mushrooms has been used for centuries within some cultures for religious and healing purposes.

This presentation, held September 15, 2020, reviewed a series of studies investigating the effects of psilocybin administered to carefully screened and psychologically prepared volunteers who were encouraged to close their eyes and direct their attention inwards.
