There are four main points to notice in this teaching. (1) The Supreme God, superior to Brahma, he who rules by grace and comprehends in his universal person the whole of existence, is Vishṇu, or Hari, represented on earth for the time being by Kṛishṇa Vāsudēva. The author makes no attempt to reconcile the fatalism implied in the old theory of _karma-saṃsāra_ with his new doctrine of special and general grace: he allows the two principles to stand side by side, and leaves for future generations of theologians the delicate task of harmonising them. (2) Three roads to salvation are recognised in principle, the intellectual gnosis of the old Upanishads and the Sāṃkhya, the "way of works" or performance of necessary social duties in a spirit of perfect surrender to God, and the "way of devotion," continuous loving worship and contemplation of God. In practice the first method is ignored as being too severe for average men; the second and third are recommended, as being suitable for all classes. (3) The way of salvation is thus thrown open directly to men and women of all castes and conditions. The Bhagavad-gītā fully approves of the orthodox division of society into castes; but by its doctrine that the performance of caste-duties in a spirit of sacrifice leads to salvation it makes caste an avenue to salvation, not a barrier. (4) The Bhagavad-gītā has nothing to say for the animal-sacrifices of the Brahmans. It recognises only offerings of flowers, fruits, and the like. The doctrine of _ahiṃsā_, "thou shalt do no hurt," was making much headway at the time, and the wholesale animal-sacrifices of the Brahmans roused general disgust, of which the Buddhists and Jains took advantage for the propagation of their teachings. I have previously spoken of the solitary passage in the Chhāndōgya Upanishad in which Kṛishṇa's name is mentioned, as receiving the teachings of Ghōra Āṅgirasa, and it will now be fitting to see how far these teachings are reflected in the Bhagavad-gītā. Ghōra compares the functions of life to the ceremonies of the _dīkshā_ (see above, p.68): and this is at bottom the same idea as the doctrine of _karma-yōga_ preached again and again in the Bhagavad-gītā. "Whatever be thy work, thine eating, thy sacrifice, thy gift, thy mortification, make of it an offering to me," says Kṛishṇa (IX. 27); all life should be regarded as a sacrifice freely offered. Then Ghōra continues: "In the hour of death one should take refuge in these three thoughts: 'Thou art the Indestructible, Thou art the Unfailing, Thou art instinct with Spirit.' On this there are these two verses of the Ṛig-vēda: Thus upward from the primal seed From out the darkness all around We, looking on the higher light, Yea, looking on the higher heaven, Have come to Sūrya, god midst gods, To him that is the highest light, the highest light."
