Question: Why are two aspects shown relying on the one mind? Answer: All dharmas naturally have these two aspects. Therefore, when Buddhas expound the Dharma, they always rely on the two truths: the aspect of the mind as tathatā is the ultimate truth, and the aspect of the mind as arising and ceasing is the conventional truth. Although spoken of as two truths, they are only a single dharma; therefore, the two truths are completely fused and inconceivable, so they each encompass all dharmas and are mutually inseparable. Moreover, the whole nature giving rise to both adverse and compliant cultivation is called the aspect of arising and ceasing; both adverse and compliant cultivation without altering the single nature is called the aspect of tathatā. Further, the whole principle forming phenomena is called the aspect of arising and ceasing; all phenomena being identical to principle is called the aspect of tathatā. Further, distinguishing phenomena and principle is called the aspect of arising and ceasing; obliterating phenomena and principle is called the aspect of tathatā. Further, provisional being identical to real is called the aspect of tathatā; real being identical to provisional is called the aspect of arising and ceasing. Further, distinguishing provisional and real is called the aspect of arising and ceasing; the non-duality of provisional and real is called the aspect of tathatā. Further, instituting the provisional for the sake of the real means explaining the aspect of arising and ceasing relying on the aspect of tathatā; opening the provisional to reveal the real means pointing out that the aspect of arising and ceasing is itself the aspect of tathatā. Further, instituting the provisional for the sake of the real and opening the provisional to reveal the real are both the aspect of arising and ceasing; principle being neither provisional nor real is called the aspect of tathatā. Further, expounding in accord with wisdom, arising and ceasing is itself the aspect of tathatā; expounding in accord with sentiment, tathatā is itself the aspect of arising and ceasing. Expounding in accord with both sentiment and wisdom, there are two aspects relying on the one mind.
