People believe that Divine incarnations happen only for the punishment of the wicked and the protection of the righteous. But these represent only one aspect of the task. The granting of peace and joy, of a sense of fulfillment to seekers who have striven long —this too is His task. TheAvatar, or form incarnate, is only the concretization of the yearning of the seekers. It is the solidified sweetness of the devotion of godly aspirants. The Formless assumes the form for the sake of these aspirants and seekers. They are the prime cause. The cow secretes milk for the sustenance of the calf. That is the chief beneficiary. But, as we see, others also benefit from that milk. So too, though the devotees are the prime cause and their joy and sustenance the prime purpose of an incarnation, other incidental benefits also accrue, such as fosteringdharma, suppression of evil, and reforming, correcting or destroying the wicked. (Bhagavatha Vahini, Ch 1, 'The Bhagavatha'.)
