大毘盧遮那經廣大儀軌 1.32

1.32

Having recited that mantra three times,
Raise the mudrā above the crown of the head
And gradually bring it down to the feet;
It can burn the aggregates and four great elements.
Because all dharmas are originally unproduced
And intrinsically quiescent,
This is the purification of the mind-ground;
Therefore it is called 'syllable burning syllable'.
Having burned the realm of sentient beings,
All dharmas are originally unproduced,
And the nature of the mind is intrinsically pure.
Next, contemplate the wheel of the syllable A,
Empowered by all Buddhas,
In color like a mass of yellow gold,
Its appearance universally square and level,
Its nature indestructible;
It is called the vajra-pṛthivīmaṇḍala.
Empower the lower body (from feet to navel);
It is called the yoga seat,
Which is the vajraratnadhātu.
