大毘盧遮那經廣大儀軌 2.13

2.13

Next, within the lotus on the right, contemplate the light disc of the syllable Saṃ,
Transforming into Mahāsthāmaprāpta, clothed in conch-shell colour,
With hands of the great compassion lotus, flourishing yet not fully opened,
Surrounded by a circular nimbus. With samādhi and prajñā hands make a hollow palm,
Like an unbloomed lotus.
