> Do not go upon what has been acquired by repeated hearing (anussava), nor upon tradition (paramparā), nor upon rumor (itikirā), nor upon what is in a scripture (piṭaka-sampadāna) nor upon surmise (takka-hetu), nor upon an axiom (naya-hetu), nor upon specious reasoning (ākāra-parivitakka), nor upon a bias towards a notion that has been pondered over (diṭṭhi-nijjhān-akkh-antiyā), nor upon another's seeming ability (bhabba-rūpatāya), nor upon the consideration 'The monk is our teacher (samaṇo no garū)' Kalamas, when you yourselves know 'These things are good; these things are not blameable; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness,' enter on and abide in them.
