[1206] Bhikkhus, when the four bases of spiritual power (iddhipāda) have been developed thus and cultivated (bahulīkata) thus, a bhikkhu wields the manifold kinds of spiritual power (iddhividha): having been one, he becomes many; having been many, he becomes one … he exercises mastery with the body even as far as the Brahmā world.
