In the whole literature of the world there are few poems worthy of comparison, either in point of general interest, or of practical influence, with the Bhagavadgītā. It is a philosophical work, yet fresh and readable as poetry; a book of devotion, yet drawing its main inspiration from speculative systems; a dramatic scene from the most fateful battle of early Indian story, yet breathing the leisure and the subtleties of the schools; founded on a metaphysical theory originally atheistic, yet teaching the most reverent adoration of the Lord of all: where shall we find a more fascinating study? Then its influence on educated India has been and still is without a rival. Everybody praises the Upanishads, but very few read them; here and there one finds a student who turns the pages of a Sūtra or looks into Sankara or Rāmānuja, but the most are content to believe without seeing. The Gītā, on the other hand, is read and loved by every educated man. Nor is there any need to apologize for this partiality: the Divine Song is the loveliest flower in the garden of Sanskrit literature.
For the Western mind also the poem has many attractions. The lofty sublimity to which it so often rises, the practical character of much of its teaching, the enthusiastic devotion to the one Lord which breathes through it, and the numerous resemblances it shows to the words of Christ, fill it with unusual interest for men of the West. But while it has many points of affinity with the thought and the religion of Europe, it is nevertheless a genuine product of the soil; indeed it is all the more fit to represent the genius of India that its thought and its poetry are lofty enough to draw the eyes of the West.
What, then, is the Gītā? Can we find our way to the fountain whence the clear stream flows?
A. When the dwelling-place of the ancient Aryan tribes was partly on the outer, partly on the inner, side of the Indus (primeval patronymic of both India and her religion), and the tribesmen were equally at home on the farm and on the battlefield, then it was that the mass of the lyrics that form the Rigveda were made. We need not stay to set forth the various ways in which this unique body of poetry is of value to modern thought. For us it is of interest because it gives us the earliest glimpse of the religion of the Indo-Aryans. That religion is polytheistic and naturalistic. The Vedic hymns laud the powers of nature and natural phenomena as personal gods. They praise also, as distinct powers, the departed fathers. Such is undoubtedly the general character of the religion of that age. On the other hand, the hymns to Varuna bring us very near monotheism indeed.
