a Section of our community earns livelihood by attending funeral rites for getting various dhans.  In olden days, in village habitats called agraharams, there were people who were carrying corpses on their shoulders to the burial ground. They were offered various dhans on various days of the rituals following the death. Sabindiharanam is a ritual when the departed soul is allowed from the predhalok to Pithru lok through offerings and prayaschithas.( predha means dead body which will attain rights to enter pithrulok - the world of souls purified only after eloborate rituals) It is believed that human birth takes place due to Paba karma done in a previous birth. We are supposed to follow dharmic path, observe our dharma as ordained in dharmic texts , not commit any paba karma in order to attain salvation so that we do not have re birth. 

those who eat on Sabindiharanam belong to the lowest strata of Brahmin society. The higher echelons do nothave marital contacts with them. They are an ostracised lot. They do not have proper education. We are supposed not to see them once they are finished with the acceptance of dhans and the feast. While lots were written about untouchability and the treatment meted out to Dalits, these poor brahmin dalits suffer humiliation and indignation more than any one else. Even the great Kanchi seer Mahaperiyava who did a lot to improve the lots of archakas, Vedic pandits probably did not think it necessary to uplift this section of the community who are denied even basic human needs. It is high time some one advocates for them and get them some privileges through provision of reservation in education and job opportunities.
