Uparichara Vasu

'Vasu, Who wanders above' IAST: UparicaraVasu [upəɾɪt͡ʃəɾəʋəs̪u]) is a king featured in Hindu literature, a member of the Chandravamsha (Lunar dynasty).

When there is a dispute that arises between the devas and the sages about the interpretation of the term 'Aja' in a Vedic injunction that prescribed for a sacrificial offering, they decide to go to Uparichara Vasu for arbitration.

[6] The Mahabharata narrates that a mountain in the king's domain, Kolahala, was once maddened by lust, and attacked a river, blocking her path.

[7] Uparichara Vasu's wife, Girika, having purified herself after bathing, informed her husband that it was an auspicious time for them to engage in intercourse.

Deciding to prioritise the instructions of his ancestors, the king sets out to the forest to hunt, thinking about his beautiful wife.

The children are brought to Uparichara Vasu, who adopts the male child, naming his Matsya, who becomes his heir.

The sage teaches him the Satvata Shastra, the knowledge of which guides his rule, and due to which he becomes a patron of the Pancharatra rituals dedicated to Narayana.

The epic also describes a legend in which Uparichara Vasu commences an ashvamedha sacrifice, but orders that no animals be slain.
