大毘盧遮那經廣大儀軌 2.172

2.172

次右蓮華中，觀㘕字法門，
無相之相光，轉成白傘頂，
普遍三千界。定羽覆五輪，
慧拳申風指。

Next, in the lotus on the right, visualise the syllable raṃ dharma-gate,
Whose light of signlessness transforms into the Sitātapatroṣṇīṣa,
Pervading the trichiliocosm. The samādhi hand covers the five fingers,
While the prajñā fist extends the wind finger.
