[243] How is wisdom (paññā) regarding what has been known the knowledge of acceptance (khantiñāṇa)? Form (rūpa) is known as impermanent; form is known as suffering (dukkha); form is known as not-self (anattā). Whatever is known, that is accepted — thus wisdom regarding what has been known is the knowledge of acceptance. Feeling (vedanā), perception (saññā), volitional formations (saṅkhārā), consciousness (viññāṇa), the eye (cakkhu) … aging and death (jarāmaraṇa) is known as impermanent; aging and death is known as suffering; aging and death is known as not-self. Whatever is known, that is accepted — thus wisdom regarding what has been known is the knowledge of acceptance. That is knowledge (ñāṇa) in the sense of what is known, and wisdom in the sense of understanding. Therefore it is said: wisdom regarding what has been known is the knowledge of acceptance.
