The caste system led to differences amongst the people. People were dissatisfied and began thinking. What was the meaning of all these rituals? What right did the brahmins have to claim themselves as superior to the rest. This spirit of enquiry prevailed towards the end of the later Vedic period.   THE UPANISHADS Upanishad is a Sanskrit word meaning sitting down near a teacher to receive instruction.

So, the people had to pay taxes to the king who appointed officials to collect them. 6.            Of all the mahajanapadas, Magadha came into prominence.

They called themselves 'Arya' meaning 'noble ones'. A new culture developed in India with the arrival of the Aryans. They did not come to India to invade and plunder and go back.
