Ratnasambhava (Lit. "Jewel-Born") is one of the Five Dhyani Buddhas (or "Five Meditation Buddhas") of Vajrayana or Tantric Buddhism. Ratnasambhava's mandalas and mantras focus on developing equanimity and equality and, in Vajrayana Buddhist thought is associated with the attempt to destroy greed and pride. His consort is Mamaki and his mount is a horse or a pair of lions.
The first documented mention of Ratnasambhava is found in the Suvarṇaprabhāsa Sūtra and in the Guhyasamāja Tantra (4th Century CE), and he subsequently appears in a number of Vajrayana texts. The most elaborate account of him is to be found in the Pañcakara section of the Advayavajrasaṃgraha.
Again in the past, immeasurable, incalculable kalpas ago, as many as the grains of sand in the Ganges River, there appeared in the world a Buddha bearing the title of Ratnasambhava Tathāgata. Any man or woman, hearing the Buddha's name and showing respect to him, will soon attain the stage of an Arhat.
Ratnasaṃbhava is associated with the skandha of feeling or sensation and its relationship with consciousness. His activity in promoting Buddhism is enriching and increasing knowledge of Dharma. Ratnasambhava is associated with the jewel symbol, which corresponds with his family, Ratna or jewel. In artwork he is shown in the mudra of giving.
He is usually coloured yellow or gold. He is associated with the element earth, the heavenly quarter of the south and the season of spring. His cardinal direction is the south. His Buddha field is known as Śrimat.
