In the Iddhipada-vibhanga Sutta, the Buddha states:
“When the four bases of spiritual power have been developed and cultivated in this way, a bhikkhu (monk) wields the various kinds of spiritual power: having been one, he becomes many; having been many, he becomes one; he appears and vanishes; he goes unhindered through a wall, through a rampart, through a mountain as though through space; he dives in and out of the earth as though it were water; he walks on water without sinking as though it were earth; seated cross-legged, he travels in space like a bird; with his hands he touches and strokes the moon and sun so powerful and mighty; he exercises mastery with the body as far as the brahmā world.”
The faithful laywoman Suppiyā had promised to provide meat to an ailing monk. After realizing there was no meat available at the market that day, she cut some flesh from her own thigh to make the offering and hid her injury. Knowing what had happened, the Buddha asked Suppiyā be brought to him. Upon seeing the Buddha, Suppiyā’s wound healed, with the laywoman’s flesh returning to what it was before with no scarring. Afterwards, the Buddha sets a rule forbidding his monks from accepting offerings of human flesh.
As his future patron Anathapindika approached him for the first time, the Buddha called him by his birth name “Sudatta”, which was not known to the public. Surprised to hear his real name, Anathapindika then concluded it could only be the Buddha who was calling him and went forward.
Walk over Water
In the Lalitavistara Sūtra, shortly after his enlightenment the Buddha heads to Varanasi to deliver his first sermon. As he reaches the Ganges River he approaches a ferryman to cross the river, who demands he pay the fee to cross the river. The Buddha responds by saying that he has no money on him and proceeds to cross the river through levitation.
Greatest Miracle of All
In the Kevatta Sutta, the Buddha describes there being three types of miracles: the miracle of psychic powers, the miracle of telepathy, and the miracle of instruction. While the Buddha acknowledged the existence of the first two miracles, he stated a skeptical person could mistake them for magic charms or cheap magic tricks. Instead, the Buddha praised the “miracle of instruction” as the superior miracle. According to the Kevatta Sutta, the miracle of instruction can lead the observer to harmlessness, virtue, and meditation; and can even eventually lead observers to the attainment of the powers of the first two miracles for themselves.
