法界次第初門 3.103

3.103

Sixth is reverent harmony through kindness in mental action. With a mind constantly abiding in the samādhi of unconditioned kindness, the bodhisattva cultivates their thought. By the power of the roots of goodness of kindness, without rising from the attainment of cessation, they manifest various mental states to bestow joy upon sentient beings; thus their mental action is in harmony with the nine destinies. They also know that the sentient beings who receive joy before them all possess Buddha-nature, the principle of the tathāgatagarbha, and in the future will definitely attain a mind like the Buddha's mind; therefore they revere them as they would a Buddha. Thus kindness in mental action is called reverent harmony.
