The other current among the Aupanishadas is flowing in a very different direction. We have seen how the worship of Rudra-Śiva has grown since the old Ṛigvēdic days, and how some souls have been able to see amidst the terrors of the god a power of love and wisdom that satisfies their deepest hopes and longings, as none of the orthodox rituals can do. A new feeling, the spirit of religious devotion, _bhakti_ as it is called, is arising among them. To them--and they number many Brahmans as well as men of other orders--Śiva has thus become the highest object of worship, Īśvara or "the Lord"; and having thus enthroned him as supreme in their hearts, they are endeavouring to find for him a corresponding place in their intellects. To this end they claim that Śiva as Īśvara is the highest of all forms of existence; and this doctrine is growing and finding much favour. Among the Aupanishadas there are many who reconcile it with the teaching of the Upanishads by identifying Śiva with Brahma. Thus a new light begins to flicker here and there in the Upanishads as the conception of Śiva, a personal god wielding free grace, colours the pale whiteness of the impersonal Brahma; and at last in the Śvētāśvatara, which though rather late in date is not the least important of the Upanishads, this theistic movement boldly proclaims itself: the supreme Brahma, identified with Śiva, is definitely contrasted with the individual soul as divine to human, giver of grace to receiver of grace. Later Upanishads will take up this strain, in honour of Śiva and other gods, and finally they will end as mere tracts of this or that theistic church. Yet another current is now beginning to stir men's minds, and it is one that is also destined to a great future. It starts from Kṛishṇa. The teaching of the Upanishads, that all being is the One Brahma and that Brahma is the same as the individual soul, has busied many men, not only Brahmans but also Kshatriyas, noblemen of the warrior order. Some even say that it arose among the Kshatriyas; and at any rate it is likely that they, being less obsessed with the forms of ritual than the Brahmans and therefore able to think more directly and clearly, have helped the Brahmans in their discussions to clear their minds of ritual symbolism, and to realise more definitely the philosophic ideas which hitherto they had seen only dimly typified in their ceremonies.
