2.236

"Or he becomes the sun and moon devas, / The Brahmā king, and the lords of worlds; / Or at times he becomes earth and water, / Or again becomes wind and fire." / Zhao says: "Encountering people drifting at sea, he transforms his body into earth, water, fire, or wind. In all cases, according to what they need, he transforms his own appearance."
