The Nirvana Sutra … set out four guidelines for judging the truth of any teaching. … These guidelines are: (1) to rely upon the Dharma, not upon persons; (2) to rely on the meaning, not on the words alone; (3)to rely on wisdom, not on knowledge alone; and (4) to rely on sutras that reveal the whole truth, not on sutras that only reveal partial truth.
