Furthermore, the *Mahāvaipulya-mahāmegha-sūtra* states: The Buddha said, "If there is a country that wishes to pray for rain, on the day of the six fasts, its king should purely bathe himself, make offerings to the Three Jewels, show reverence, utter praise, and call upon the names of the nāga kings. Good son, the natures of the four great elements may be altered, but that one should recite and uphold this incantation and heaven not bring down rain—that is impossible. Because there are divine spells in this scripture, for the sake of sentient beings, the Buddhas of the three periods of time have all proclaimed it together."
