Suppose there was a light tuft of cotton-wool or kapok. Taken up by the wind, it would easily rise up from the ground into the air. In the same way, sometimes the Realized One submerges his body in his mind and his mind in his body. He meditates after sinking into a perception of bliss and lightness in the body. At that time his body easily rises up from the ground into the air. He wields the many kinds of psychic power: multiplying himself and becoming one again … controlling the body as far as the realm of divinity.”

“Mendicants, there are these four bases of psychic power. What four? It’s when a mendicant develops the basis of psychic power that has immersion due to enthusiasm … energy … mental development … inquiry, and active effort. These are the four bases of psychic power. By developing and cultivating these four bases of psychic power, a mendicant realizes the undefiled freedom of heart and freedom by wisdom. And they live having realized it with their own insight in this very life due to the ending of defilements.”
