One of the Five Buddha Families
Among the four activities, Ratnasambhava embodies the activity of enrichment, which his yellow color symbolizes. Ratnasambhava sits on a lotus-and-full-moon-disc throne upheld by eight horses. In ancient times, horses were the swiftest means of transportation, so the swiftness of the eight horses represents the speediness or impulsiveness of our pride and arrogance.
The right hand of Ratnasambhava holds a widh-fulfilling gem, signifying that Ratnasambhava can effortlessly fulfill the wishes of sentient beings the moment they turn and open their minds to him. His left hand holds a bell, signifying that he fulfills these wishes in a pleasing and gentle manner.
