大毘盧遮那經廣大儀軌 2.59

2.59

Next, one should proceed to the wind quarter, contemplating again the wrathful honoured one,
Namely Trailokyavijaya. First visualize him upon a jewel rock,
Within the Fire-Generating Samādhi, the syllable-gate Ha revolving,
Conceive the awe-inspiring wrathful honoured one, surrounded by bright fierce flames,
Jewelled crown, holding a vajra, disregarding his own bodily life.
His mudrā is the same as Vajrajñāna, exclusively inviting to receive the teachings.
