The Bhagavad-gîtâ identifies Kṛishṇa with Vâsudeva and with Vishṇu but does not mention Nârâyaṇa and from its general style I should imagine the Nârâyaṇiya to be a later poem. If so, the evolution of Bhâgavata theology will be that Kṛishṇa, a great hero in a tribe lying outside the sphere of Brahmanism, is first identified with Vâsudeva, the god of that tribe, and then both of them with Vishṇu. At this stage the Bhagavad-gîtâ was composed. A later current of speculation added Nârâyaṇa to the already complex figure, and a still later one, not accepted by all sects, brought the pastoral and amorous legends of Kṛishṇa. Thus the history of the Bhâgavatas illustrates the Indian disposition to combine gods and to see in each of them only an aspect of the one. But until a later period the types of divinity known as Vishṇu and Śiva resisted combination. The worshippers of Śiva have in all periods shown less inclination than the Vishnuites to form distinct and separate bodies and the earliest Śivaite sect of which we know anything, the Pâśupatas,[493] arose slightly later than the Bhâgavatas. 5 Patañjali the grammarian (_c._ 150 B.C.) mentions devotees of Śiva[494] and also images of Śiva and Skanda. There is thus no reason to doubt that worshippers of Śiva were recognized as a sect from at least 200 B.C. onwards. Further it seems probable that the founder or an early teacher of the sect was an ascetic called Lakulin or Lakulîśa, the club-bearer. The Vâyu Purâṇa[495] makes Śiva say that he will enter an unowned corpse and become incarnate in this form at Kâyârohana, which has been identified with Kârvân in Baroda. Now the Vâyu is believed to be the oldest of the Purâṇas, and it is probable that this Lakulin whom it mentions lived before rather than after our era and was especially connected with the Pâśupata sect. This word is derived from Paśupati, the Lord of cattle, an old title of Rudra afterwards explained to mean the Lord of human souls. In the Sâṅtiparvan[496] five systems of knowledge are mentioned. Sâṅkhya, Yoga, the Vedas, Pâśupatam and Pâncarâtram, promulgated respectively by Kapila, Hiraṇyagarbha, Apântaratamas, Śiva the Lord of spirits and son of Brahmâ, and "The Lord (Bhagavân) himself." The author of these verses, who evidently supported the Pâncarâtra, considered that these five names represented the chief existing or permissible varieties of religious thought. The omission of the Vedânta is remarkable but perhaps it is included under Veda. Hence we may conclude that when this passage was written (that is probably before 400 A.D. and perhaps about the beginning of our era) there were two popular religions ranking in public esteem with the philosophic and ritual doctrines of the Brahmans. The Mahâbhârata contains a hymn[497] which praises Śiva under 1008 names and is not without resemblance to the Bhagavad-gîtâ. It contains a larger number of strange epithets, but Śiva is also
