釋禪波羅蜜次第法門 3.32

3.32

答曰：心雖非上下，為治沈浮患故，上下安之，於行無失。若心浮動，可作意下著止之；若心沈沒，可上著止之。復次，若下著安心，利益眾多，略說有二：一、心易得定；二者、眾病不生。

Answer: Although the mind is neither above nor below, in order to cure the troubles of sinking and floating, placing it above or below incurs no fault in practice. If the mind floats and stirs, one can intentionally place it below to stop it; if the mind sinks and submerges, one can place it above to stop it. Furthermore, if one places and settles the mind below, the benefits are numerous, briefly stated as two: first, the mind easily attains absorption; second, various illnesses do not arise.
