二、明防守正念，謂前恐六根起過，住於正念防守六根。今時後恐念有忘失，故攝受多聞學聞思修。由三慧力獲得正念念不忘失，是則三慧防守正念，為欲令此所得正念無忘失故時時修習三慧不息。

Second, clarify protecting right mindfulness: previously, fearing that the six faculties would give rise to faults, one abides in right mindfulness to protect the six faculties. Now, subsequently fearing that mindfulness will be forgotten and lost, one assimilates extensive learning and trains in hearing, thinking, and cultivation. By the power of the three wisdoms, one attains right mindfulness and mindfulness is not forgotten or lost; thus, the three wisdoms protect right mindfulness. In order to cause this attained right mindfulness to not be forgotten or lost, one constantly cultivates the three wisdoms without ceasing.
