I was on my facebook account earlier, and I saw one of my friends had posted the following.  It couldn’t be more true.  Take a look:

Your eyes can shift from love to hate, serenity to jealousy, in an instant. This happens every time you react to a given situation. The key to controlling your glances is found in a concept called resistance. Namely you resist the desire to react to instinctive impulses. Not only does this action of resistance prevent you from casting angry or jealous eyes at another person, it also helps you achieve your purpose in life.

How?

The moment you resist a reactive egocentric response, you find your true self – a proactive soul. That means you find the Light and fulfillment in that specific circumstance. When you react, you are not a creator. You are simply an effect. The person or situation that caused you to react is the cause. But when you resist reaction, you are now the cause of your emotion and the creator of your consciousness. That means fulfillment is now free to flow to you.
