The pre-Aryan society, like many other European, Polynesian and East African societies, already had certain horizontal divisions of the people, with upper and lower classes. This was conveniently added to the theories of Varnas. As the 'Vedic Aryans' from North moved to the South, the Priests met with the 'Dravidian Kings'. Both groups, with all the fights they had, wanted to perpetuate their dynastic rules and to keep their positions for ever. They both saw the benefits by this and modified the Vedic teachings to suit their own classes in society. The Gunas and Varnas were mistaken for familial characters, assuming sons of educators and warriors shall be educators and warriors, to their advantage. They were misinterpreted by the priests and kings, to guarantee the progeny an assured vocation of the family, very much like a trade union guarantee. As people moved from place to place and new vocations were taken up, new subclasses were also introduced, each one claiming superiority over others, at the same time accepting inferiority to some others at all levels of the Hindu Society for ever.

The "Law of Karma" and rebirths were also used conveniently to perpetuate this practice. People at the lower end of the ladder insisted more on these laws and accepted it more violently and practiced it, for the fear of wrath of the "Gods". As Vedic rules and rituals became strict, people who did not follow these teachings and Dharma became outcasts and untouchables. In the early Vedic times, people in one class could achieve entering other classes and intermarriage was an acceptable practice. They could study the Scriptures to become the priests or become warriors and kings or Merchants by appropriate study and training. This changed with times as the Kshathriya kings started ruling the small kingdoms in Central India and several other parts of India. During the time of "Later Puranas and Later Dharshanas", about 900- 1000 AD, inter-community marriages and inter-dining were denied and became a taboo. All these prejudices and burden of classes had to be carried on by the children of successive generations of the society and there were no escape from it to any one except in rebirth by "Good Karma ".
