Ratnasambhava, 'the Jewel-Born', is the Buddha of the south in the five-Buddha mandala, yellow or golden in colour, seated with the right hand open in the varada mudra of giving and holding the wish-fulfilling jewel (cintamani) of the ratna family. His wisdom is the wisdom of equality (samata-jnana): the seeing that all beings are of one taste, which the tradition treats as the antidote to pride and to the grasping that ranks beings above and below. He is almost entirely a mandala Buddha — unlike Amitabha he has no independent sutra cult of his own, and his place in Buddhist practice comes through the tantric mandalas and the five-Buddha visualisations rather than through a scripture addressed to him.
Modern Practice
Tibetan practitioners meet him in the mandala offering and in the visualisation of the five Buddhas, and he is invoked in generosity and wealth practices — the jewel in his hand is for giving away, not for keeping. Modern Western readings file him as a Buddhist abundance deity; the tradition's own emphasis is the equality of beings, and the giving is the practice rather than the reward.
