Mind your battery

Take care of that battery; yes, that one. The one that is running your life; the one inside of you that you owe your consciousness and the functions of your body to. You were born with a functioning battery, and it will continue to operate until the moment you die. How is one to take care of this battery?
First, a battery needs liquid, water with some electrolytes, to help generate the electricity. In the body, this is the cerebrospinal fluid. A body in dehydration all the time can not generate the electricity to have all the body's parts function optimally. Second, there has to be two poles to create the electricity, and in the body these are the North Pole end at the brain and the South Pole end at the sacrum. The electrolytes are gathered and balanced as only the body knows how to do, from the food and beverages one eats. Interference from most diseases, including mental disease, drug therapies, poor diet, and even nutritional supplements which create imbalances will disturb the ability of the battery to maintain a strong charge. It is the charge on the battery which determines the vigor with which one can live. The goal of yoga can not be reached unless optimal physical and mental integration occurs, and this depends on a strong battery charge.
Do genetics play a part in all this? Of course, genetics is the playground upon which all the other factors register, interact, and produce the output.
So take care of that battery: drink enough water, eat healthy, get a modicum of exercise, and keep a positive attitude. Then if you so deem it the proper moment to seek a taste of cosmic consciousness and awareness of the total energy flows within/without, use this health to forge a bond to your Creator.

For our Creator so loved his humans, that...

each and every person was gifted with a spirit within, which is none other than the electrical core of the body and its distribution networks, and the ability to self-recognize this phenomenon.
This electrical center appears as a Light to those who reach the integration of conscious and unconscious minds (mind being the energy flow in the realm of the conscious or unconscious). Only those who have experienced the Light know it as a fact; others will always doubt its existence because they have not been shown, through their experience or by accident, that within them is a wonderful spiritual world which has a Light shining at its center.

Don't drift too far

When one falls off the wagon, don't fall so far away that it is hard to climb back on. Your center is lost that way, and the farther you fall the more distant from your Creator you become. Then joy is difficult to find in life.
