The Ancient City in Samut Prakan (Muang Boran)
After Lord Buddha had attained enlightenment, he enjoyed the happiness of emancipation. In the sixth week, during which time Lord Buddha was in the joy of freedom under a big tree, east of the Phrasimaha Bodhi Tree, a heavy rainstorm broke out.
Then appeared the Mujjalint Naga, a seven-headed serpent residing in a big pond near where Lord Buddha was seated. The serpent coiled itself into the form of a seven-tiered seat for Lord Buddha and spread his head like an umbrella to protect the Lord from the rainstorm.
