Know and watch your heart. It's pure but emotions come to colour it. So let your mind be like a tightly woven net to catch emotions and feelings that come, and investigate them before you react.
Ajahn ChahLearn to see that it is not things that bother us, that we go out to bother them. See the world as a mirror. It is all a reflection of the mind. When you know this, you can grow in every moment, and every experience reveals truth and brings understanding.
