[114] There is passing on from one basis (vatthu), and turning away by perception (saññā); adverting (āvajjana) is indeed a power, and reflection (paṭisaṅkhā) and insight (vipassanā); by inference from the object, both are defined as one; resolution upon cessation (nirodha) is insight having the characteristic of fall. Having reflected on the object, one contemplates its dissolution, and there is its appearance as empty: this is insight of higher wisdom (adhipaññāvipassanā). One skilled in the three contemplations and in the four insights, through skill in the three appearances, does not waver amid the various views. That is knowledge (ñāṇa) in the sense of what is known, and wisdom in the sense of understanding. Therefore it is said: wisdom in contemplating dissolution, having reflected on the object, is knowledge of insight (vipassanā). ___________
