Definition - What does Avesha mean?
Avesha is a Sanskrit word that has a number of possible translations, including, “endowed” and “occupation by any sentiment or feeling.” It can also be taken to mean “indirect.” It is used in Hinduism to refer to an incarnation of a representative of a god or goddess. This is in contrast to sakshat, which refers to a direct incarnation of a deity or their avatar.
The appearance of an avesha deity in Hindu scripture and mythology is usually a temporary event.
Yogapedia explains Avesha
When an avesha avatar is created, they are empowered by the deity to do their work on earth for them, so that the deity does not need to descend directly to earth. Their incarnation is likely to be for a specific cause or reason, hence its temporary nature.
One of the best known examples of an avesha is the Parasurama Avatar of Lord Vishnu. Parasurama Avatar was created to have Lord Vishnu’s destructive power in so that he could destroy evils spirits and demons. This occurred because the world was in peril. However, it is said that when extremely powerful evils wreak havoc on world, God himself will appear in a direct incarnation rather than an avesha.
