"Disciples of the Buddha should listen attentively: next to the east, in the third court,
Is the wish-granting vajra altar. Square and everywhere uniform,
Guarded with the vajra mudrā, therein one should make
The fire-born maṇḍala; inside the heart again place
The wondrous and good blue lotus mudrā. The Wise One, Mañjughoṣa,
Surrounded by his root mantra, arranging the bīja according to the ritual,
And taking that as the seed. Furthermore, on its four sides,
Adorn with blue lotuses, surrounding and forming the assembly of diligent noble ones."
