大毘盧遮那經廣大儀軌 2.119

2.119

In the north is the honored one Kṣitigarbha, whose seat is exquisitely adorned;
the ground is embellished with various jewels,
interwoven and alternating in color.
Within a four-jeweled lotus, visualize the light-wheel of the syllable ha,
which transforms into the honored one Kṣitigarbha.
The samādhi and prajñā hands form fists inwardly,
extending and releasing the banners of the fire wheels.
Abiding in the vajra-indestructible
samādhi, he speaks the mantra.
