It is said that crystals have the ability to transmute dark energy into light. They do so by changing the frequency at which the energy resonates. Every thought and emotion has a vibrational frequency associated with it. Crystals can alter this frequency, which is why they are commonly used at spiritual ceremonies. The human body has surprising similarities to crystals. They are both composed of a carbon base. In fact, there are several companies that offer to turn cremated ashes into diamonds. If you have the money, you can have the ashes of your loved one turned into a diamond for remembrance.
Now, if an inanimate object like a crystal has the ability to transmute dark energy into light and the human body has similar properties, perhaps you have the same ability.
One reason why people like to work out, is because it produces an endorphin response in the mind. Endorphins are a part of the pleasure/reward endocrine system in the body. Alcohol and drugs like Heroin, play on the same system, which is why they are so addictive. These addictions can actually be replaced with heavy exercise. Leading a person down a road of health and fulfillment, rather than the downward spiral that drugs offer. AA which stands for Alcoholics Anonymous, can also stand for Attitude Adjustment. All a person really needs to do, is work out rather than use drugs in order to feel good and deal with personal demons.
Many people will drink or use drugs in order to drown pain and anger. That same emotion can be taken out in the gym. Feelings of anger and frustration can be used as energy to lift the weight. If you use that energy up until it's gone, I assure you, it will be transmuted into something positive. When a person looks good as a result of going to the gym, that is only a secondary reward. the primary reward is feeling good.
