The Vedas laid down injunctions and prohibitions. They regulated the actions of men, propelled by Kâma or desire. Men must eat meat. The Vedas said this meat was prohibited, but that could be used. Men mixed with women. The Vedas laid down restrictions. Even they regulated the relations between man and wife. Then the Vedas laid down the duties which men owed to all classes of beings. In order to induce men to accept the Vedic injunctions, the Vedas held out Svarga as the reward of Vedic Karma. They even favoured the belief, that there was to be immortal life in Svarga gained by the performance of Vedic Karma. Detailed rules as to the performance of Vedic sacrifices were given. So long as men did not aspire to become Indra, or the ruler of Svarga, the Devas were pleased with the sacrifices; they helped the performer as much as they could, giving them all objects of desire, and they welcomed them to Svarga, when they passed to that plane after death. The Devas were as friendly to the performer of Vedic Karma as they were unfriendly to the immature Trisanku. The Vedic Karma Kânda became thus fully revealed. The revelation was made in the last Treta-yuga of the present Manvantara. "At the beginning of the Treta Yuga, the three Vedas were revealed through Pururavas." IX. 14-49. "The path of Karma was promulgated in Treta Yuga, by the division of the Vedas." _Śridhara_. The great churning was justified. The Devas asserted themselves for the good of humanity. The Rishis got the revelation and helped men to place themselves in active relationship with the Devas. Men learned to regulate themselves and to give up the wantonness of material life. And they had a strong inducement to do so in the prospect of eternal life in Svarga. The great actor in this Vedic movement was Rishi Visvâmitra, (Hallowed be his name!) Others followed him in quick succession, and there was a brilliant combination of Vedic Rishis who propounded the whole of the Karma Kânda of the Vedas, as it was revealed to them by the force of Kâlpic necessity. At all times there have been two parties, one following the current of evolution, and another going against it. At all times there have been cavillers and sceptics. The Haihayas and Tâlajanghas were confirmed materialists and great sinners. They ridiculed the Brâhmanas, who performed Vedic Karma, and often set themselves in opposition to them. They were very troublesome to the Brâhmanas. King Sagar wanted to extinguish the race, but he was prevented from doing so. Possibly Atlantis was the country inhabited by these races and Nature helped the cause of evolution by dragging down the continent itself under water. The sacred Gangâ also flowed at this time, spreading purity over all lands lying on her banks.
