Be like a broken gong when it comes to the opinions of the world. The words may strike the mind but they don't have to reverberate inside. Let the opinions of fools be like water falling off a duck’s back.
Perceive the voice of a worldling as if it is the wind blowing through leaves, or the strange vocalisations of a creature that arises and ceases. Just sound, nothing more.
One doesn't have to follow the herd if it's going in the wrong direction. Choose your own way.
