What is "suryaprabha"

Suryaprabha is a bodhisattva whose specialty is sunlight and good health. Suryaprabha is often seen with Candraprabha, as the two siblings serve Bhaisajyaguru. Statues of the two closely resemble each other and are commonly found together, sometimes flanking temple doors. They are also known in mainland Asia, but as devas rather than bodhisattvas.
