大毘盧遮那經供養次第法疏 1.38

1.38

From "In order to make them firm" onward is the twelfth gate, the Vajrasattva Mantra, which solidifies the body of Dharma; here also are mudrā, mantra, and verse. "Making them firm" means wishing to solidify the body and mind of the practitioner who cultivates relying upon the Dharmadhātu-Origination. "Contemplating one's own vajra body" means being identical with the body of Vajrasattva. The two gāthā lines from "Binding the vajra-wisdom mudrā" onward explain the mudrā to be performed. The two lines "That person shall not long [after]", etc., manifest the benefit of performing the mudrā. The two lines "Mantra mudrā", etc., reveal the characteristics seen by the Savior of the World. The two lines "Constantly turning like a precious wheel", etc., within what is seen by the Savior of the World, cite the phenomenal precious wheel as an analogy for the Dharma precious wheel.
