“In the LSD state the boundaries between the experiencing self and the outer world more or less disappear, depending on the depth of the inebriation.”
Source: LSD : My Problem Child (1980), Ch. 11 : LSD Experience and Reality
Context: What constitutes the essential, characteristic difference between everyday reality and the world picture experienced in LSD inebriation? Ego and the outer world are separated in the normal condition of consciousness, in everyday reality; one stands face-to-face with the outer world; it has become an object. In the LSD state the boundaries between the experiencing self and the outer world more or less disappear, depending on the depth of the inebriation. Feedback between receiver and sender takes place. A portion of the self overflows into the outer world, into objects, which begin to live, to have another, a deeper meaning. This can be perceived as a blessed, or as a demonic transformation imbued with terror, proceeding to a loss of the trusted ego. In an auspicious case, the new ego feels blissfully united with the objects of the outer world and consequently also with its fellow beings. This experience of deep oneness with the exterior world can even intensify to a feeling of the self being one with the universe. This condition of cosmic consciousness, which under favorable conditions can be evoked by LSD or by another hallucinogen from the group of Mexican sacred drugs, is analogous to spontaneous religious enlightenment, with the unio mystica. In both conditions, which often last only for a timeless moment, a reality is experienced that exposes a gleam of the transcendental reality, in which universe and self, sender and receiver, are one.

“Science depends on outer experiment. Spirituality depends on inner searching and seeking.”
Songs of the Soul (1971)
Context: Science depends on outer experiment. Spirituality depends on inner searching and seeking. A scientist discovers the power that very often threatens even his own life. A spiritual seeker discovers the power that guides and moulds his life into a life of divine fulfilment.
