When the Lord Buddha was in his bodhisatta (Pali) (Thai: โพธิสัตว์, phothisat) incarnation as King of the Toads Phaya Khang Khok (), and married to Udon Khuruthawip (, Northern Partner-Knowing-Continent), his sermons drew everyone, creatures and sky-dwellers alike, away from Phaya Thaen (), King of the Sky).
Naga Rockets fired in the air at the end of the hot, dry season are not to threaten Phaya Thaen, but to serve as a reminder to him of his treaty obligations made to Lord Bodhisatta Phaya Khang Khok, King of the Toads, down on the ground.
