The Legend of Bang Fai Phaya Nark
When the Lord Buddha was in his Bodhisatta Phaya Kan Kark incarnation, he incarnated in Sida's belly. When he grew up and practice his pray, Lord Indra made him a very good-looking person and also gave Udorn Kurutaweeb to be his wife. The couple regularly studied Dhama and gave sermon to all kinds of beings.
Both human and other beings admired and greatly had faith on the sermons of Lord Bodhisatta Phaya Kan Kark. They then forgot to dedicate offerings to Phaya Tan, the God who created the beings and rainfall for the earth.
Phaya Tan then became very angry because he did not receive any offerings from human and beings. Moreover, all the angels who are usually around him had gone to attend the sermon peformed by Phaya Kan Kark.
The angry Phaya Tan then condemned all of the beings by not making any rainfall for the total period of seven years, seven months, and seven days. The drought then spread to the whole earth. Human beings then urged to Lord Bodhisatta and asked for his help.
Phaya Kan Kark then realized, by his sight, and told the human that Phaya Tan did not receive offerings and became angry, hence resulting in not making rainfall for seven years. When Phaya Nagi, a mythical serpent and the king of the underworld, who was attending the sermon knew the cause, he then took his troops to attack Phaya Tan who lived in heaven, despite the advice against from Lord Bodhisatta Phaya Kan Kark.
But Phaya Nagi lost to Phaya Tan and was heavily wounded. Lord Bodhisatta Phaya Kan Kark felt sympathize and he considered that Phaya Nagi did all for the happiness of mankind. He then blessed Phaya Nagi and the followers.
