Vishvedevas

This name can either be construed as
referring to all the gods, based on the
term’s literal meaning (“all the gods”), or
it can refer to a group of deities reckoned as the sons of Vishva, the daughter of the divine sage Daksha. The
number of sons differs according to different texts and is reckoned at either ten
or thirteen. The Vishvedevas are especially worshiped at the memorial rites
for the dead known as shraddhas,
although the Manu Smrti, one of the
authoritative texts in the dharma literature, prescribes offerings to them every
day. These prescribed daily offerings are
said to have been their reward for having performed particularly harsh asceticism (tapas).
