2.7

一切菩薩法式悉知。諸佛祕藏無不得入　此難因果德滿。因知菩薩修行之法。或果入諸佛化物之祕藏三蜜而七言偈明　肇曰。諸佛身口意祕密之藏。

"He knows all the rules and ceremonies of bodhisattvas, and enters all secret treasuries of the Buddhas." This praises the perfection of the virtues of cause and fruit. Through the cause, he knows the bodhisattva's methods of cultivation; through the fruit, he enters the secret treasuries of the Buddhas in transforming beings. The three secrets are clarified in seven-character verses. Zhao says: The secret treasuries of the Buddhas' body, speech, and mind.
