When we are children, and we have a problem with someone, we get angry.  For whatever reason, that anger pushes the problem away, and we get the results we want.  It happens a second time - we react with anger - and now we know if we get angry we push the problem away.  Then we practice and practice, until we become a master of anger.

In the same way, we become masters of jealousy, masters of sadness, masters of self-rejection.  All of our drama and suffering is by practice.  We make an agreement with ourselves, and we practice that agreement until it becomes a whole mastery.  The way we think, the way we feel, and the way we act become so routine that we no longer need to put our attention on what we are doing.  It is just by action-reaction that we behave in a certain way. 

To become masters of love, we have to practice love.  The art of relationship is also a whole mastery, and the only way to reach master is with practice.  To master a relationship is therefore about action - it's not about concepts of attaining knowledge.  It is about action.
