Marici, meaning shining in buddha mythology is a Buddhist (Mahayana) astral goddess.
She is an emanation of Vairocana, also his Shakti. This deity is further identified as a bodhisattva, or buddha-designate. Also she may be the mother of Sakyamuni (a form of the Buddha).
She is considered the equivalent of the Hindu Surya. Marici may be depicted in a three-headed form, as the Shakti of Hayagriva, with the left head being that of a pig.
She rides in a chariot drawn by seven boars. Her color is red, yellow, or white, and attributes are the arrow, fly whisk, horse’s head in the hair, needle, prayer wheel, staff, sword, thread and trident; also in three-eyed.
In Hindu, Marici designates a demiurge, a product of the creator god Brahma
