When they meet at midnight, they are hungry ghosts who are covered in fire and encounter great embarrassment (Guanyin Bodhisattva incarnation).

If you can give the six gods through diet and provide us with three treasures, you can increase your fortune and prolong your life. The next morning, Ananda told the Buddha about it, so the Buddha read the Dalagni mantra and said diet therapy.
