According to Osho, the first four bodies carry alternating male/female polarities; through inner intercourse the positive and negative poles unite—first with second, then successively—creating wholeness within. As these inner pairs fuse, the restless drive for outer union subsides. When all four sheaths are balanced, polarity is neutralized and the fifth body arises beyond sex; male–female distinctions end in a single, fulfilled consciousness.
When the opposite parts inside your first four layers join and balance, by the fifth layer there’s no ‘male’ or ‘female’ left—just calm, whole awareness.
