Published Summer of ’23 Andrew Newberg’s Sex, God, and the Brain revisits ideas that were big in the late 19th and early 20th century among authors who propounded theories of Solar Phallic Worship as the foundation of all known religions. This then became the foundation of the various theories and practices we now know as Sex Magick. Posted description of this book is:

From neuroscientist Andrew Newberg, Sex, God, and the Brain argues that our religious and spiritual experiences derive directly from our sexual being.  While others have speculated on a connection between religion and sex, Newberg is the first to demonstrate—with groundbreaking brain scan research gained through Orgasmic Meditation studies—that the underlying biological mechanism of religious, spiritual, and sexual experiences are identical.

With research technical enough for academics, but explained simply enough for the everyday reader, Sex, God, and the Brain, will reframe our understanding of the link between spirituality and sexuality.
