“Do not simply believe whatever you are told, or whatever has been handed down from past generations, or what is common opinion, or whatever the scriptures say. Do not accept something as true merely by deduction or inference, or by considering outward appearances, or by partiality for a certain view, or because of its plausibility, or because your teacher tells you it is so. But when you yourselves directly know, “These principles are unwholesome, blameworthy, condemned by the wise; when adopted and carried out they lead to harm and suffering,” then you should abandon them. And when you yourselves directly know, “These principles are wholesome, blameless, praised by the wise; when adopted and carried out they lead to welfare and happiness,” then you accept and practice them.” Buddha
