Osho never wrote a book titled simply Ego . However, several of his books and talk compilations focus heavily on the ego, including:

A significant portion of the "Osho Ego" literature is dedicated to explaining the mechanics of how the ego operates. Osho describes the ego as a divider. Its primary function is to separate the individual from the whole. It draws a line and says, "I am." For this "I" to exist, it must constantly assert itself against something else—the "Thou" or the world.

According to Osho, the ego is a societal imposition. It is born the moment the child looks into a mirror or is addressed by others.
