At any rate, we find that, before the Brahmanical Age had ended, the conception was becoming more prevalent of a supreme personal god, greater than Indra or Agni, and worthy of minds influenced by the Upanishads—a god who was the embodiment of the First Cause, an Infinite Being uncontrolled by the priesthood. One section of the people appears to have worshipped Vishnu as the Celestial incarnation of the World Soul, while another gave recognition to Shiva. In the absence of records, however, it is impossible to ascertain to what extent monotheistic ideas were developed by unorthodox teachers. The new doctrines may have degenerated, like Buddhism, as they became widespread. It is evident, however, that the priesthood were unable to ignore them, for they are referred to in their “books”.

Although the political prominence of Vishnu and Shiva belong to the Age of reformed Brahmanism, it is undoubted that both deities were worshipped throughout the long period of Buddhistic ascendancy. The Greek ambassador Megasthenes, who resided in India between B.C. 311 and 302, and wrote Ta Indika, furnishes interesting evidence in this connection. “By his description of the god Dionysus, whom they worshipped in the mountains, Shiva”, says Professor Macdonell, “must be intended, and by Herakles, adored in the plains ... no other can be meant than Vishnu and his incarnation Krishna.... These statements seem to justify the conclusion that Shiva and Vishnu were already prominent as highest gods, the former in the mountains, the latter in the Ganges valley.... We also learn from Megasthenes that the doctrine of the four Ages of the World (Yugas) was fully developed in India by this time.”[165]

In the Rigveda Vishnu is a god of grace. He is, however, a secondary deity—an attribute of the sun and a phase of Agni. From the earliest times, it is significant to note, his benevolent character is emphasized. In one of the hymns[166] he is called “the Kinsman”; he welcomed to his heaven of bliss the faithful worshippers of the gods. An interesting reference is made to his “highest step”. As detailed in later writings, the myth involved is to the effect that the demon Bali, one of the dreaded Danavas (Titans), had, in the Treta Yuga, secured temporary ascendancy over the gods. Vishnu appeared before him in the form of the dwarf Vamana, and requested as much territory as he could measure out by taking three strides. The demon granted this request, and Vishnu immediately assumed the form of a giant; his first step covered the heavens, the second crossed the entire earth, and the third and highest reached the abode of the gods. So was the Universe won back from the Asuras. It is believed that the myth refers to the progress of the conquering sun by day and by night.

In Yajurveda Vishnu is more prominent than in the Rigveda, and in the Brahmanas “there is a growing tendency”, remarks Professor Barnett, “to regard him as a blessed Cosmic Spirit”.[167] He is fully identified with Brahma in the Mahábhárata. In some of the myths he is the source of Indra's strength and valour, and he appears to have absorbed the sublime character of Varuna, the god of sinners; he is similarly associated with the sea, but the Sea of Milk.

Shiva is a development of the Vedic storm god Rudra, who was not only dreaded, but also revered as a destroyer of evil-doers, hatred, evil, and disease, and as a nourisher who gave long life.[168]

Both deities inspired love and reverential fear; they won the affections of human hearts and were worshipped emotionally. Their cults have had independent doctrinal development, however, and they divide Hinduism to-day into two great churches, one of which recognizes Vishnu, and the other Shiva, as the greatest god. Their union in the Trinity has not yet obliterated sectarian differences.

Many myths have collected round Vishnu, originally a purely abstract deity, because the faith which he represents had to be imparted to the masses in “parables”. These “parables” were, of course, given literal interpretation by the people. The majority of the myths belong to the post-Buddhist Age—the Age of Brahmanical revival, during which came into existence the sacred poems called the Puranas. Many were also incorporated in the great epics, the Mahábhárata and the Ramáyana, which existed in part, at least, before the rise of Buddhism and Jainism.

When Vishnu, the god of mercy and goodness, received recognition as Narayana in the Brahmanical Age, he was worshipped as the “unconquerable preserver” who at the dawn of each Yuga (Age) awoke as the child of the primordial waters. In one myth he rises from a lotus bloom; in another he is supposed to sleep, as Brahma, on the coils of the world-serpent Shesha, which is “a part of a part of Vishnu”. This serpent rests on the tortoise, Kurma, another form of Vishnu. When the tortoise moves its limbs, Shesha is roused to yawn; thus are earthquakes caused. A creation myth which teaches the absolute supremacy of Vishnu tells that at the beginning Brahma sprang from a lotus issuing from the navel of the Preserver, while Shiva came from his forehead.
