Aryans withoyt caste - 6

...The Rig Vedic Aryans took up the agriculture with an inordinate delay of 600 years. They came to India in about 1500 BC and took up agriculture only in later Vedic period, which starts from 900 BC onwards. But before they could take up the agriculture and form large village based communities one more thing had to happen. This was the demise of Rig Vedic way of life of communes. It was the end of Rita, the cosmic order, which was the religion of Rig Vedic people. The Rig Vedic dharma emphasized on commune living, common ownership of tribal wealth (cattle stock) and equal distribution of tribal wealth and captured cows. In addition it meant devotion to Vedic gods and fire mode of worship and a cosmic order. Only fire worship, thread ceremony and Rig Veda were to survive and rest of the things were confined to dustbin of history.

This dharma called Rita was later to be replaced by eternal Sanatan dharma based on Chaturvarna system which was to make living hell out of lives of uncountable people in coming ages. The sickening durability of this hellish system is surprising.

Over a period of time especially in the later Vedic period (or later three Vedas), the agriculture came to acquire a prominent place in the Aryan society when they took up the superior occupation of defeated native people. By this time the Aryans had lost the character of a race and got intermixed with local people through mixing of blood and alliances with local kings with whom the Rig Vedic people had won and lost many wars. But they were winners, ultimately, through diplomatic and war like means. Their region extended from Sapta-Sandhav to Ganga and Yamuna with many Janapadas and Mahajanapadas (small kingdom like territories). As a result of this intermixing, the color of skin had changed from white to light brown and other darker versions. The Vedic people settled on land copying the technique of agriculture of native people. The small tribes combined and formed big tribes. These big tribes in turn formed small kingdoms in the upper northern parts of Indian sub-continent...
