Caste system is pervasive in India. It invades almost every religion in India over time. As an example, here’s what I wrote in another response. This Jati is so pervasive in India that even the non-Hindu religions such as Sikhism and “Lingayat” which were explicitly formed to be away from the Hindu caste system couldn’t escape it. So we now have a few dozen Jati within Sikhism and Lingayats with an overly of Verna.
