OSM Sex Matters
Much of this material originally published as "Sex to Superconsciousness" which I read in Osho's Ashram in the late 70s.
He's still the Master of the Century in my book. revolutionary, perceptive, poetic, sensitive, funny, and deeply allergic to sacred cows !
In this book Osho gives so much insight and advice, making it all as simple as Life or Death :-)
