When Be Here Now was first published in 1971, it filled a deep spiritual emptiness, launched the ongoing mindfulness revolution, and established Ram Dass as perhaps the preeminent seeker of the twentieth century.

Just ten years earlier, he was known as Professor Richard Alpert. He held appointments in four departments at Harvard University. He published books, drove a Mercedes and regularly vacationed in the Caribbean. By most societal standards, he had achieved great success. . . . And yet he couldn’t escape the feeling that something was missing.

Psilocybin and LSD changed that. During a period of experimentation, Alpert peeled away each layer of his identity, disassociating from himself as a professor, a social cosmopolite, and lastly, as a physical being. Fear turned into exaltation upon the realization that at his truest, he was just his inner-self: a luminous being that he could trust indefinitely and love infinitely.
