大毘盧遮那經廣大儀軌 1.87

1.87

By the power of the mantra and mudrā, turning the vajra mudrā thrice,
it streams and disperses like firelight, its radiance universally pervading
all Buddha fields; with a mind free of doubts,
it flows forth everywhere. On the vajra path of the three realms,
within it is the palace of the dharmadhātu, a vast jewel pavilion,
in the center of which visualize the maṇḍala.
Next, form the mudrā of turning the wheel of the Dharma, like that in the Sarvatathāgatatattvasaṃgraha.
