We need to keep a constant watch over our mind and learn to distinguish between the beneficial and harmful thoughts that are arising moment by moment. Those who are able to do this are truly wise.
Patience is a mind that is able to accept fully and happily, whatever occurs. It is much more than just gritting our teeth and putting up with things. Being patient means to welcome wholeheartedly whatever arises, having given up the idea that things should be other than what they are.
Patient acceptance is often considered a weak and passive response to problems that we do not have the power or courage to solve. In reality, however, being patient is far from being passive. There is nothing strong or courageous in reacting to hardship or insults with anger - all we are doing is being defeated by our delusions.
