The things we say and do in life become grand gestures of our innermost goodness or representations of the ugliness we harbor and lock away. Regardless which side of this you spend most of your time dwelling on the important thing to realize is that, though every moment of our lives is valuable, moments themselves are fleeting. What lingers on with us is not the moment but the emotion we felt from that moment. Feelings, you see, are what compose us, not moments. So do we have a choice in our emotion? Do we get to choose which emotions we hang onto? This is a tricky question as it seems as though emotion is more like an act of God, uncontrollable and unpredictable. The good news is that emotion is also a habit. Just like everything else. Our emotions are slaves to our thoughts and, in turn, we are slaves to our emotions. So, it would appear that we have circled back into choice of thought patterns.
All any emotion is is a combination of chemicals released into your nervous system by the hypothalamus gland. Not only does this gland's chemicals control emotion, but also hunger, thirst, balance, etc. In extreme cases, that gland releases too much or too little of a certain chemical and medication is the only way to rectify the imbalance. But for most people a simple choice in thought can reprogram the hypothalamus to release different combinations of chemicals. The hypothalamus is like our own, internal drug dealer. We think and it creates a batch of "stuff" suited to our thoughts. Then it sends that batch out into our bloodstream where it hunts for cells to infect. If you've ever known a drug addict then you know that after awhile they need more and more and more of the drug to get the desired affect. Our cells are similar, they become addicts to chemicals and crave more of certain ones. We are all addicted to different emotions, our cells screaming at us from the inside out for the chemicals we have gotten them addicted to based on our thoughts. This is one of the reasons that so many scientists say that stress causes aging. Stress is an overload of chemicals and those chemicals are bombarding your cells. This bombardment eventually damages the cells ability to take in important proteins and amino acids which in turn begins to affect health. With these unhealthy cells dwelling around inside of you, your skin loses elasticity at rapid rates and before you know it you look haggard. One more example of why healthy thought patterns are so important.
It's like that pendulum swing of love. While you're in it, you're glowing, you feel energized, healthier even. But then, when it's over, you can feel physically ill, tired, and miserable. Ever wonder why that is? It is because the person feeling love is merely getting an excess of a happy chemical from their hypothalamus gland. So when "love" dies, people are almost like addicts having withdrawals from the chemical which they had become so accustomed to feeling in their bloodstream.
