[244] How is it that wisdom (paññā), through the state of having touched (phuṭṭhattā), is knowledge (ñāṇa) of fathoming (pariyogāhana)?
One touches form (rūpa) as impermanent (anicca), touches form as suffering (dukkha), touches form as not-self (anattā); whatever one touches, that very thing one fathoms — thus wisdom, through the state of having touched, is knowledge of fathoming. One touches feeling (vedanā), perception (saññā), volitional formations (saṅkhārā), consciousness (viññāṇa), the eye (cakkhu) … aging and death (jarāmaraṇa) as impermanent, touches them as suffering, touches them as not-self; whatever one touches, that very thing one fathoms — thus wisdom, through the state of having touched, is knowledge of fathoming.
That is knowledge (ñāṇa) in the sense of what is known, and wisdom in the sense of understanding. Hence it is said: wisdom, through the state of having touched, is knowledge of fathoming.
