“Until philosophers rule as kings or those who are now called kings and leading men genuinely and adequately philosophise, that is, until political power and philosophy entirely coincide, while the many natures who at present pursue either one exclusively are forcibly prevented from doing so, cities will have no rest from evils,... nor, I think, will the human race." (Republic 473c-d)”
― Plato, The Republic

“In the ancient Indian Upanishads, the answer to the question “Who am I?” is “Tat tvam asi.” This succinct Sanskrit sentence means literally: “Thou art That,” or “You are Godhead.” It suggests that we are not namarupa—name and form (body/ego), but that our deepest identity is with a divine spark in our innermost being (Atman) that is ultimately identical with the supreme universal principle (Brahman). And Hinduism is not the only religion that has made this discovery. The revelation concerning the identity of the individual with the divine is the ultimate secret that lies at the mystical core of all great spiritual traditions. The name for this principle could thus be the Tao, Buddha, Cosmic Christ, Allah, Great Spirit, Sila, and many others.”

“LSD was not a pharmacological agent generating exotic experiences by its interaction with the neurophysiological processes in the brain. This remarkable substance was clearly an unspecific catalyst of the deep dynamics of the human psyche. The experiences induced by it were not neurochemical artifacts, symptoms of a toxic psychosis as mainstream psychiatrists called it, but genuine manifestations of the human psyche itself.”
