The Brahmanas develop a sharper social divide by suggesting the ideal occupations of the ideal varnas in society. For example:

a. They classified certain social categories as untouchables.

b. According to the brahmins, the Chandalas were considered as untouchables.

c. It was based on the concept that some activities especially those that are connected with the performance of rituals were sacred and pure.

d. Those who considered themselves as pure avoided taking food from the so-called untouchables.
