Three bite hardest. Karma's account of suffering, critics argue, blames victims and rests on a beginningless ignorance it never explains (Whitley Kaufman presses this in "Karma, Rebirth, and the Problem of Evil"); the tradition answers that karma is diagnosis rather than blame, and that a beginningless ignorance is no stranger than any other ultimate starting point. Ambedkar's Annihilation of Caste charged that caste is not an add-on but built into the scriptures' authority itself; reformers respond by subordinating every text to the Upanishads' one self in all. Third, the schools flatly contradict one another about ultimate reality; the classical reply — teachings are staged to the student's capacity — persuades insiders more than critics.
