仁王護國般若波羅蜜多經疏 2.463

2.463

The commentary states: This reiterates the previous question. First it clarified the increasing of the practice of self-benefit through the five kṣāntis; next it stated that the ten kings excel in the practice of benefiting others; if both self-benefit and other-benefit are to be contemplated, this is shown in summary. "Contemplation" (guan) means illuminating wisdom; "investigation" (cha) means examining carefully; because of illuminating and carefully examining, it is called "observing and investigating" (guancha). Second, following upon this, is clarifying abiding in equanimity.
