40. How do you justify the caste system in Hinduism?

The Gita says that the caste is due to qualities and profession (Guna Karma Vibhagasah). Qualities were always respected. Rama and Krishna were non-Brahmins. The Brahmin priests wash the statues of Rama and Krishna and swallow it as sacred water. In Bhagavatam it is written that Bhuri Sravasa, who is a pot maker was made Brahma in the sacrifice. Ravana was a Brahmin but was condemned. Every human being is ‘Sudra’ by birth and can become Brahmin by practicing the true meaning of the Vedas (Janmana Jaayate). Brahmana means he who knows Brahman. Brahman also means the Veda in Sanskrit. Every caste contains good people as well as bad people. Sabari and Kannappa belong to the family of untouchables. Nobody is untouchable by birth. In the Veda only four castes were mentioned. How this fifth caste came into existence? All the bad people in the four castes were expelled from the village just like a bad student is expelled from the school. Thus untouchability is due to the qualities and deeds but not by birth. Brahmins are worshipping the photos of Sabari and Kannappa in their prayer rooms
