I shall treat elsewhere of his philosophy, known as the Viśishṭâdvaita or non-duality, which yet recognizes a distinction between God and individual souls. The line of thought is old and at all periods is clearly a compromise, unwilling to deny that God is everything and yet dissatisfied with the idea that a personal deity and our individual transmigrating souls are all merely illusion. Devotional theism was growing in Râmânuja's time. He could not break with the Upanishads and Vedantic tradition but he adapted them to the needs of his day. He taught firstly that the material world and human souls are not illusion but so to speak the body of God who comprises and pervades them: secondly this God is omniscient, omnipresent, almighty and all-merciful, and salvation (that is mukti or deliverance from transmigration) is obtained by those souls who, assisted by his grace, meditate on him and know him; thirdly this salvation consists not in absorption into God but in blissful existence near him and in participation of his glorious qualities. He further held[587] that God exists in five modes, namely: (_a_) Para, the entire supreme spirit, (_b_) the fourfold manifestation as Vâsudeva, Saṅkarshaṇa, Pradyumna and Aniruddha, (_c_) incarnations such as Râma and Kṛishṇa, (_d_) the internal controller or Antaryâmin according to the text[588] "who abiding in the soul rules the soul within," (_e_) duly consecrated images. The followers of Râmânuja are at present divided into two schools known as Tengalais and Vadagalais, or southern and northern.[589] The double residence of the founder is one reason for the division, since both Mysore and Trichinopoly could claim to have personal knowledge of his teaching. The really important difference seems to be that the Tengalai or southern school is inclined to break away from Sanskrit tradition, to ignore the Vedas in practice and to regard the Tamil Nâlâyiram as an all-sufficient scripture, whereas the Vadagalais, though not rejecting the Nâlâyiram, insist on the authority of the Vedas. But both divisions are scrupulous about caste observances and the ceremonial purity of their food. They are separated by nice questions of doctrine, especially as to the nature of prapatti, resignation or self-surrender to the deity, a sentiment slightly different from bhakti which is active faith or devotion. The northerners hold that the soul lays hold of the Lord, as the young monkey hangs on to its mother, whereas the southerners say that the Lord picks up the helpless and passive soul as a cat picks up a kitten.[590] According to the northerners, the consort of Vishṇu is, like him, uncreated and equally to be worshipped as a bestower of grace: according to the southerners she is created and, though divine, merely a mediator or channel of the Lord's grace. Even more important in popular esteem is the fact that the Vadagalai sectarian mark ends between the eyebrows whereas the Tengalais prolong it to the tip of the nose.
