釋禪波羅蜜次第法門 3.126

3.126

如《涅槃經》說：「欲知真金，應三種試之，謂燒、打、磨。」行人亦是，難可別識。若欲別之，亦須三種試之，所謂當與共事；共事不知，當與久處；久處不知，以智慧觀察。今借此意以明禪定邪、正之相。如發一動觸，若邪正未了，應當深入定心，於所發境中不取不捨，但平心定住。若是善根定力踰深，善根踰發，若魔所為，不久自壞。

As the Nirvāṇa Sūtra says: "If one wishes to know genuine gold, it should be tested in three ways, namely, burning, striking, and grinding." Practitioners are also like this: difficult to distinguish and recognize. If one wishes to distinguish them, they must also be tested in three ways, namely: one should work together with them; if one does not know them by working together, one should dwell with them for a long time; if one does not know them by dwelling with them for a long time, one observes them with wisdom. Now, I borrow this intention to clarify the corrupt and correct marks of dhyāna absorption. For instance, when a moving sensation arises, if corrupt and correct are not yet clear, one should enter deeply into a concentrated mind, neither grasping nor rejecting within the realm that has arisen, but simply stabilizing with a level mind. If it is a wholesome root, the deeper the power of absorption becomes, the more the wholesome root arises; if it is the work of Māra, it will naturally disintegrate before long.
