_Dharma_ alone, however, could not directly achieve this end. This could be done by the path of _yoga_ or self-discipline--a path which involved penances, meditation and asceticism. By ridding his mind of all desires and attachments, by concentrating on pure abstractions, the ascetic 'obtained insight which no words could express. Gradually plumbing the cosmic mystery, his soul entered realms far beyond the comparatively tawdry heavens where the great gods dwelt in light and splendour. Going "from darkness to darkness deeper yet," he solved the mystery beyond all mysteries; he understood, fully and finally, the nature of the universe and of himself and he reached a realm of truth and bliss, beyond birth and death. And with this transcendent knowledge came another realization--he was completely, utterly, free. He had found ultimate salvation, the final triumph of the soul.'[5] Such a complete identification with the supreme Spirit, however, was not easily come by and often many existences were required before the yogi could achieve this sublime end. 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.
