The Hindu society of four varnas based on virtues, profession and nature, degenerated into caste system with branches and sub branches, based on birth only. It also created untouchability and depressed classes. Swami Dayanand tried to bring back varna system on right lines. This also included creation of unity in Hindu Society and to eliminate restrictions on sharing meals and having marriage alliances.
One day a person brought meals for Swamiji. He was a 'nai' (Barber). A person remarked that the bread was of 'nai' a low caste Hindu and should not be accepted. Swami Dayanand observed. "The bread is of wheat only" and accepted the meals from 'nai'.
