Suppabuddha

Suprabuddha (Sanskrit), or Suppabuddha (Pali) was the maternal uncle and father-in-law of the Buddha according to the Mahavamsa genealogy and the Theravada commentarial tradition. He was also known as Mahāsuppabuddha.

Suppabuddha is also the name of several other individuals mentioned briefly in the Theravada tradition.

Life
According to the Theravada commentaries, One day, the path leading to the Supreme Buddha and the monks was blocked by King and company. The Supreme Buddha saw the evil that was going on and warned three times but did not listen. Buddha later returned with the monks. King Suprabuddha also returned because his wish was granted. Later, when Ananda Thera inquired about this incident, the Supreme Buddha preached that sending a Buddha back was a great sin. Because of that sin, the king would flee the earth in seven days and go to hell.

Informed of this prediction, the king sealed himself up on a high floor of his palace as a precaution. However, on the seventh day predicted by the Buddha, a horse belonging to the king broke loose and the king went to attempt to calm it. He fell down the stairs and was swallowed by the earth, sharing the same eventual fate as his son, Devadatta.
