大毘盧遮那經廣大儀軌 2.4

2.4

At the north-east intermediate direction, upon a great lotus pedestal, contemplate the light disc of the syllable Yaṃ,
Which transforms into the Mother of All Buddhas, radiant with genuine gold colour,
Wearing plain white cloth as garments, illuminating everywhere like the sunlight,
Directly receiving and abiding in samādhi, named Gaganalocanā,
The Vidyārājñī Gaganalocanā.
