If you are talking about Dayand Saraswati, he is a 18th century philosopher. You cannot cite 18th century philosopher's word as today's. Please quote a statement by BJP or RSS which supports Varna system in recent age(25 years).

In old age people used to believe earth is in the center of the universe. One should not quote anything which is more than 25 years old. World is changing rapidly.

How many believes that now except few delusioned individuals who still believe earth is flat and is in the center of the universe and rest of the talks are propaganda?
