仁王護國般若波羅蜜多經疏 2.197

2.197

Exposition: "The three realms" refers to the locus of reliance. "Causes and effects" refers to karmic causes and consciousness effects, which are that which can produce. Observing that which is influenced and that which influences, one attains the three kṣāntis: regarding the three realms and their causes and effects as possessing real substantiality, observing that what is imagined is empty, one attains emptiness kṣānti; the pure tathatā revealed by this emptiness is devoid of the ten signs, hence one attains signlessness kṣānti; defiled causes and effects arise from false karma, and cultivating practice based on this, one does not wish for them, attaining wishlessness kṣānti. Third from here is confronting and observing the two kṣāntis.
