大毘盧遮那經廣大儀軌 1.92

1.92

Having recited that mantra, rotate the mudrā three times;
a halo of light universally appears, and within the wheel the Buddhas and bodhisattvas
are the support of all things—the practitioner's yoga seat.
With body identical to the Vajradhara, using the syllable RA as the visual field,
it shines and blazes like a bright lamp. Lower the neck and incline the head slightly,
with the tongue resting near the palate, and thereby contemplate the place of the mind.
In the mind appears meditative absorption (samāhita), stainless and exquisitely pure;
a round mirror constantly manifests before oneself. Such is the true mind:
the yogin transforms the syllable, entering the practice of the maṇḍala,
visualizes all the great assemblies, trains in eyes of loving-kindness and compassion,
and contemplates the realm of sentient beings. Entering the amṛta samādhi,
by virtue of this very samādhi power, proclaims the vidyā-queen
of unobstructed power throughout all three times.
