Ratnasambhava is one of the Five Tathāgatas, often called the Five Dhyani Buddhas in modern English-language writing. He belongs especially to Vajrayāna Buddhist mandala systems and is associated with the southern direction, the jewel family, generosity, and the wisdom of equality.

Name and meaning
The Sanskrit name Ratnasambhava can be understood as “Jewel-Born” or “Source of Jewels.” Jewel imagery suggests richness, value, generosity, and inexhaustible awakened qualities.
He is not the historical Buddha Gautama and is not a creator god.
Color and direction
In common five-Buddha mandalas, Ratnasambhava is associated with yellow or golden color and the southern direction.
Mandala details can vary between tantric systems, so attributes should be checked within the particular lineage or text.
Gesture and symbols
Ratnasambhava is often shown with the right hand in the gesture of generosity or giving. Jewel imagery and the horse may also be associated with his Buddha family in particular systems.
These elements communicate a network of symbolic meanings rather than a biographical portrait.
Wisdom of equality
Vajrayāna systems commonly associate Ratnasambhava with the wisdom of equality, which sees beings without the distortions of pride and status.
The corresponding transformation is often described as turning pride or possessiveness into equanimity, generosity, and recognition of shared awakened potential.
Place among the Five Tathāgatas
Ratnasambhava is usually presented with Vairocana, Akṣobhya, Amitābha, and Amoghasiddhi. Together they structure mandalas, initiations, contemplations, and symbolic maps of awakening.
Why he matters
Ratnasambhava represents a Vajrayāna vision in which ordinary mental afflictions can be transformed into forms of awakened wisdom and compassionate activity.
