There remained a third way--the path of _bhakti_ or devotion to God. If a
man loved God not as an abstract spirit but as a loving Person, if he
loved with intensity and singleness of heart, adoration itself might
obtain for him the same reward as a succession of good lives. Vishnu as
protector might reward love with love and confer immediately the blessing
of salvation.

The result, then, was that three courses were now open to a man and
whether he followed one or other depended on his own particular cast of
mind, the degree of his will-power, the strength of his passions and
finally, his capacity for renunciation, righteousness and love. On these
qualifications the upshot would largely depend. But they were not the only
factors. Since gods and demons were part of the world, a man could be
aided or frustrated according as gods or demons chose to intervene. Life
could, in fact, be viewed from two angles. On the one hand it was one long
effort to blend with the Godhead--an effort which only the individual
could make. On the other hand, it was a war between good and evil, gods
and demons; and to such a contest, God as Vishnu could not remain
indifferent. While the forces of evil might properly be allowed to test or
tax the good, they could never be permitted completely to win the day.
When, therefore, evil appeared to be in the ascendant, Vishnu intervened
and corrected the balance. He took flesh and entering the world, slew
demons, heartened the righteous and from time to time conferred salvation
by directly exempting individuals from further re-births.

It is these beliefs which govern the _Mahabharata_ epic and provide the
clue to Krishna's role. Its prime subject is a feud between two families,
a feud which racks and finally destroys them. At the same time, it is very
much more. Prior to the events narrated in the text, Vishnu has already
undergone seven incarnations, taking the forms of a fish, tortoise, boar
