大毘盧遮那經廣大儀軌 2.1

2.1

To the east of Mahāvairocana Tathāgata, on a great white lotus pedestal,
Within a perfectly pure moon disc, inside appears a conch-shell colour.
Contemplate the dharma-gate of the syllable Khaṃ, triangular and radiating brilliant light,
Its colour entirely pure white, surrounded by vajra mudrās.
From that king of mantras, light radiates all around,
Flowing forth universally; holding this subdues the four Māras.
It is named the Universal Knowledge Mudrā, capable of fulfilling manifold merits;
The mind of all those Buddhas, named the Greatly Zealous.
