Caste system hierarchically divides the society. A sense of highness and lowness or superiority and inferiority is associated with this gradation or ranking. The Brahmins are placed at the top of the hierarchy and are regarded as pure or supreme. The degraded caste or the untouchables have occupied the other end of the hierarchy. The status of an individual is determined by his birth and not by selection nor by accomplishments. Each caste has its own customs, traditions practices and rituals.It has its own informal rules, regulations and procedures. The caste panchayats or the caste councils regulate the conduct of members. The caste system has imposed certain restrictions on the food habitats of the members these differ from caste to caste. In North India Brahmin would accept pakka food only from some castes lower than his own.
But he would not accept kachcha food prepared with the use of water at the hands of no other caste except his own. As a matter of rule and practice no individual would accept kachcha food prepared by an inferior casteman.The caste system put restriction on the range of social relations also. The idea of pollution means a touch of lower caste man would pollute or defile a man of higher caste. Even his shadow is considered enough to pollute a higher caste man. The lower caste people suffered from certain socio-religious disabilities. The impure castes are made to live on the outskirts of the city and they are not allowed to draw water from the public wells. In earlier times entrance to temples and other places of religious importance were forbidden to them. Educational facilities, legal rights and political representation were denied to them for a very long time. If the lower castes suffer from certain disabilities some higher caste like the Brahmins enjoy certain privileges like conducting prayers in the temples etc.There is gradation of occupations also. Some occupations are considered superior and sacred while certain others degrading and inferior. For a long time occupations were very much associated with the caste system. Each caste had its own specific occupations which were almost hereditary. There was no scope for individual talent, aptitude, enterprise or abilities. The caste system imposes restrictions on marriage also. Caste is an endogamous group. Each caste is subdivided into certain sub castes which are again endogamous.Intercaste marriages are still looked down upon in the traditional Indian society.
