Katthahari Jataka

A beautiful poor woman once gave birth to an illegitimate son of the King of Benares. When the infant grew up, she took him to the King and said, “ Oh King, accept your son.” The King denied this with anger and shame. Being left with no alternatives, the woman said, “I shall toss him into the air. If he is your son, he will hover. If not, he will fall down and die.” She tossed the child into the air, and he did not fall. This proved the truth. The baby boy was the Bodhisattva (a previous life of the Buddha).
