"Only One Sky" is the title of a transcript of a series of morning discourses given by Bhagwan Shree Rajneesh in Poona, India, in February 1975. The discourses are a commentary and interpretation of the Song of Mahamudra which were the teachings transmitted from Tilopa, the 11th century "father" of Tibetan Buddhism, to his primary disciple Naropa, who then told Marpa, who then told Milarepa, who told two friends, and, well, you know how it goes. The same discourses were also published under the title, "Tantra: The Supreme Understanding" but are best appreciated in Rajneesh's own voice on MP3. The book had a profound and deeply transformative influence on my life, as did my time with Rajneesh in Poona.
From discourse [HASHTAG]#9[/HASHTAG]: "A natural man simply sits inside and allows things to happen. He does not ”do.” And Tilopa says only then does Mahamudra appear; the final, the utterly final orgasm with the existence. Then you are separate no more. Then your inner sky has become one with the outer sky. There are not two skies then, only one sky."
