Dutiyasamaṇabrāhmaṇa sutta: Ascetics and Brahmins (2nd)

“Mendicants, all the ascetics and brahmins in the past, future, or present who wield the various kinds of psychic power—multiplying themselves and becoming one again; materializing and dematerializing; going unobstructed through a wall, a rampart, or a mountain as if through space; diving in and out of the earth as if it were water; walking on water as if it were earth; flying cross-legged through the sky like a bird; touching and stroking with the hand the sun and moon, so mighty and powerful; controlling the body as far as the realm of divinity— do so by developing and cultivating the 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. Mendicants, all the ascetics and brahmins in the past, future, or present who wield the many kinds of psychic power—multiplying themselves and becoming one again … controlling the body as far as the realm of divinity— do so by developing and cultivating these four bases of psychic power.”
