Have you ever noticed that once you express something...it comes back to haunt you?
What do I mean? When we set ourselves up to comment on a particular lesson we have to learn, or we are in judgment over an action by someone else, or we are feeling particularly "proud" of ourselves for our achievement. WHAM! Whatever we are expressing from a point of separation is drawn to us so that we may PRACTICE right action.
What is right action?
Right action might be considered neutralizing our tendency to react. It is the ability to have the things we project once again turned toward us so that we are the recipients of those projections. If we can get our egos out of the way, we can see how perfectly the law of cause and effect works - how instantaneously our own inner thoughts of condemnation or whatever is mirrored right back so that we have an opportunity to "right" the original action/reaction. We might have the projection played back to us in several ways or repetitiously until we "get" it until we no longer need to project that separateness.
And projections also come to us of a positive nature. Those are much more fun! It would be an interesting exercise to watch our projections throughout the day. What are we putting out (projecting) and what is coming back? How much is positive and how much negative, and in spite of WHAT it is, how often are we able to maintain neutrality?
