Ritual use of psychedelic plants and substances has been a particularly effective technology for inducing holotropic states of consciousness - Stanislav Grof

All the cultures in human history except the Western industrial civilization have held holotropic states of consciousness in great esteem. They induced them whenever they wanted to connect to their deities,other dimensions of reality, and with the forces of nature. They also used them for diagnosing and healing, cultivation of extrasensory perception, and artistic inspiration. They spent much time and energy to develop safe and effective ways of inducing them.

In the last few decades, it has become increasingly clear that humanity is facing a crisis of unprecedented proportions. Modern science has developed effective measures that could solve most of the urgent problems in today's world--combat the majority of diseases, eliminate hunger and poverty, reduce the amount of industrial waste, and replace destructive fossil fuels by renewable sources of clean energy. 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.

In one of my early books I suggested that the potential significance of LSD and other psychedelics for psychiatry and psychology was comparable to the value the microscope has for biology or the telescope has for astronomy. My later experience with psychedelics only confirmed this initial impression. These substances function as unspecific amplifiers that increase the cathexis (energetic charge) associated with the deep unconscious contents of the psyche and make them available for conscious processing. This unique property of psychedelics makes it possible to study psychological undercurrents that govern our experiences and behaviours to a depth that cannot be matched by any other method and tool available in modern mainstream psychiatry and psychology. In addition, it offers unique opportunities for healing of emotional and psychosomatic disorders, for positive personality transformation, and consciousness evolution.
