My dear friend VT Rajshekhar believes that "If Hinduism goes, Marxism goes and if Marxism goes, Hinduism goes." With 4 Varnas, 6854 cults and communities in one religion in India he may be right. I heard about this book in 1980's but the printed form we found in 2015 only. It needs to be available in pdf format and to be xeroxed for easy distribution.
