大毘盧遮那成佛經疏 20.8

20.8

The fifth is named Mṛṇa, which means 'harmonious union'. This deity is light yellow in color, meaning yellow combined with the color of fire. 'Harmonious union' means that it combines two aspects. His icon has a wrathful expression on the left side and a joyful, smiling form on the right side, each occupying half of the body. This subtle smile is neither anger nor great joy, but abiding in serenity. He has hair on his body, meaning that whiskers, sideburns, and hair are somewhat abundant, but they must not be excessive; if excessive, they would mar his dignity. His neck is long and he has great majestic radiance. As for his body color, one side is red and one side is yellow (the wrathful side should be red). His seat is also [composite]: the right is square (half vajra-seat), and the left is triangular (half fire-seat). His left [hand] holds a knife, and his right [hand] holds a vajra. There are two rituals, internal and external, modeled on the previous ones. This harmonious union can accomplish both summoning and pacifying disasters throughout all places. Its internal application is the light of wisdom, through which afflictions are extinguished as unborn. When performed externally, the incense, flowers, and garments must also be of two kinds; during recitation, one also visualizes oneself in this form identical to the primary deity, with one eye wrathful and one eye serene, so that disasters are removed and wishes are fulfilled, all accomplished simultaneously. Because of this principle of equal ubiquity, there is such efficacy, unlike partial and one-sided teachings.
