Don't rely on logic alone, nor speculation. Don't infer or be deceived by appearances.

Be a lamp unto yourself.

Know well what holds you back, and what moves you forward

The world is afflicted by death and decay. But the wise do not grieve, having realized the nature of the world.

This Ariyan Eightfold Path, that is to say: Right view, right aim, right speech, right action, right living, right effort, right mindfulness, right contemplation.

So in this case, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering' - then you should abandon them.

Yet the Teaching is simple. Do what is right. Be pure. At the end of the way is freedom.
