Śankara was a native of southern India. It is not easy to combine in one picture the progress of thought in the north and south, and for the earlier centuries our information as to the Dravidian countries is meagre. Yet they cannot be omitted, for their influence on the whole of India was great. Greeks, Kushans, Huns, and Mohammedans penetrated into the north but, until after the fall of Vijayanagar in 1565, no invader professing a foreign religion entered the country of the Tamils. Left in peace they elaborated their own version of current theological problems and the result spread over India. Buddhism and Jainism also flourished in the south. The former was introduced under Asoka but apparently ceased to be the dominant religion (if it ever was so) in the early centuries of our era. Still even in the eleventh century monasteries were built in Mysore. Jainism had a distinguished but chequered career in the south. It was powerful in the seventh century but subsequently endured considerable persecution. It still exists and possesses remarkable monuments at Sravana Belgola and elsewhere. But the characteristic form of Dravidian religion is an emotional theism, running in the parallel channels of Vishnuism and Śivaism and accompanied by humbler but vigorous popular superstitions, which reveal the origin of its special temperament. For the frenzied ecstasies of devil dancers (to use a current though inaccurate phrase) are a primitive expression of the same sentiment which sees in the whole world the exulting energy and rhythmic force of Siva. And though the most rigid Brahmanism still flourishes in the Madras Presidency there is audible in the Dravidian hymns a distinct note of anti-sacerdotalism and of belief that every man by his own efforts can come into immediate contact with the Great Being whom he worships. The Vishnuism and Śivaism of the south go back to the early centuries of our era, but the chronology is difficult. In both there is a line of poet-saints followed by philosophers and teachers and in both a considerable collection of Tamil hymns esteemed as equivalent to the Veda. Perhaps Śivaism was dominant first and Vishnuism somewhat later but at no epoch did either extinguish the other. It was the object of Śankara to bring these valuable but dangerous forces, as well as much Buddhist doctrine and practice, into harmony with Brahmanism.
