The Caste Question in Hindu Scriptures

Caste was a colonial conspiracy imposed by the British Raj as THE social system of Hindus.  Modern Indian politicians embrace castes because they find it useful for creating and maintaining vote banks. Caste is eroding Hindu culture. Our fight against caste is based on debating with the help of Hindu Scriptures, which we call Shastrartha. This book serves as a Shastrartha against caste. Even though this book does not extensively cover the teachings, it still touches on all the main points that I am aware of.
I intended to reintroduce you to varna, jati, kula, varna-sankara, svabhava svadhama, and varna-sharama dharma as they are presented in the Scriptures. I imagined that I was speaking directly to my reader, and I hope he or she will take this seriously. Caste affects every Hindu, so we all must get involved.
