Mandala of the Mystic Law is the teacher who leads all people to Buddhahood and enlightenment

Though this mandala has but five or seven characters, it is the teacher of all Buddhas throughout the three existences and the seal that guarantees the enlightenment of all women. It will be a lamp in the darkness of the road to the next world and a fine horse to carry you over the mountains of death. It is like the sun and moon in the heavens or Mount Sumeru on earth. It is a ship to ferry people over the sea of the sufferings of birth and death. It is the teacher who leads all people to Buddhahood and enlightenment. 22/2
