Now the moral law, in order that it may be feared, needs to be embodied in the personality of a god. Most of their gods inspire no fear at all in the souls of the Brahmans; but there is one of whom they have a dread, which is all the greater for being illogical. Prajapati is a vast impersonality, too remote and abstract to inspire the soul with either fear or love. The other gods--Indra, Agni, Soma, Varuna, Vishnu, and the rest--are his offspring, and are moved like puppets by the machinery of the ritual of sacrifice created by him. However much they may seem to differ one from another in their attributes and personalities, they are in essence one and negligible in the eyes of the master of the ritual lore. In the beginning, say the Brahmanas, all the gods (except Prajapati, of course) were alike, and all were mortal; then they performed sacrifices and thereby became immortal, each with his peculiar attributes of divinity.[18] Thus at bottom they are all the same thing, merely phases of the universal godhead, waves stirred up by the current of the cosmic sacrifice. They have no terrors for the priesthood. But there is one deity who obstinately refuses to accommodate himself to this convenient point of view, and that is Rudra, or Siva. By rights and logically he ought to fall into rank with the rest of the gods; but there is a crossgrained element in his nature which keeps him out. As we have seen, he comes from a different source: in origin he was a demon, a power of terror, whose realm of worship lay apart from that of the gods of higher class, and now, although it has extended into the domains of orthodox religion, an atmosphere of dread still broods over it.[19] Rudra wields all his ancient terrors over a much widened area. The priests have assigned him a regular place in their liturgies, and fully recognise him in his several phases as Bhava, Sarva, Ugra, Maha-deva or the Great God, Rudra, Isana or the Lord, and Asani or the Thunderbolt (KB. VI. 2-9). Armed with his terrors, he is fit to be employed in the service of conscience. Hence a myth has arisen that in order to punish Prajapati for his incest with his daughter the gods created Bhuta-pati (who is Pasu-pati or Rudra under a new name), who stabbed him. The rest of the myth is as immaterial to our purpose as it is unsavoury; what is important is that the conscience of the Brahmans was beginning to feel slight qualms at the uncleanness of some of their old myths and to look towards Rudra as in some degree an avenger of sin. In this is implied an immense moral advance. Henceforth there will be a gradual ennoblement of one of the phases of the god's character. Many of the best minds among the Brahmans will find their imaginations stirred and their consciences moved by contemplation of him. To them he will be no more a mere demon of the mountain and the wild. His destructive wrath they will interpret as symbolising the everlasting process of death-in-life which is the keynote of nature; in his wild dances they will see imaged forth the everlasting throb of cosmic existence; to his terrors they will find a reverse of infinite love and grace. The horrors of Rudra the deadly are the mantle of Siva the gracious. Thus, while the god's character in its lower phases remains the same as before, claiming the worship of the basest classes of mankind, and nowise rising to a higher level, it develops powerfully and fruitfully in one aspect which attracts grave and earnest imaginations. The Muni, the contemplative ascetic, penetrates in meditation through the terrors of Siva's outward form to the god's inward love and wisdom, and beholds in him his own divine prototype. And so Siva comes to be figured in this nobler aspect as the divine Muni, the supreme saint and sage.
