Rely on the Law and not upon persons

Everyone believes in those Buddhist teachers who were revered in their own time. But the Buddha enjoins us in the Nirvana Sutra as his final instruction, "Rely on the Law and not upon persons." The Buddha taught us to rely on the sutras if the Buddhist teachers should be in error. You say those teachers could not possibly be in error, but between the Buddha's golden words and your personal opinion, I am committed to the former. 24/6
