The term “Two Truths” is mentioned in many Sūtras, but its principle is difficult to understand. The world is in an uproar and has debated this issue for a long time. A Sūtra [the Miao-sheng-ting Ching] says, “In the past the Buddha and Mañjuśrī had a dispute over the Two Truths, and they both fell into hell. It was not until the time of the Buddha Kāśyapa that their doubts were resolved satisfactorily.” If these two sages in their causal stages [previous to attaining Buddhahood] were unable to understand completely, how is it possible for people with strong emotional passions?
