In Buddhist psychology, the word samyojana refers to internal formations, fetters or knots. When someone says something unkind to us, for example, if we do not understand why he said it and we become irritated, a knot will be tied in us. The lack of understanding is the basis for every internal knot. It is difficult for our mind to accept that it has negative feelings like anger, fear, and regret, so it finds ways to bury these in remote areas of our consciousness. We create elaborate defense mechanisms to deny their existence, but these problematic feelings are always trying to surface. If we practice mindfulness, we can learn the skill of recognizing a knot the moment it is tied in us, so that the work of untying them will be easy. Otherwise, they will grow tighter and stronger.
