The story tells that on one occasion, the Buddha was dwelling at the Veluvan monastery in Rajagaha. One day, the monks assembled in the Dhamma pavilion and talked about the virtues and power of the Buddha. At the time, the Buddha had just finished exercising devils in Vesali. Then, the Buddha delivered a sermon to the monks and told the story of his previous life. Bodhisatta was born as Suvannakhankhak (King golden toad). The toad fought with Phaya Thaen (God king) and conquered the fighting. Then Phaya Thaen gives rains to Suvannakhankhak as his present since then until these days.
