Chinese Medicine has loads of information on how to improve virility, increase life expectancy, become more potent, etc. Some of it is ancient hoo-doo, [sleeping with a slew of virgins, as, say, opposed to your wife does not increase anything in your own body.] Some of it is based on really sound principles, tested and proven over several thousand years, like supplementing kidney jing and chi through acupuncture, herbs and lifestyle modifications.
Jing is the life force we are all born with. Some of us have more than others. Want to see it in action? Look at pictures of any president at the beginning of his term and four or eight years later. Big difference. He’s burned out/used up his jing at an accelerated rate. Or check out speed freaks. What meth does to them is, in effect, extremely accelerated aging. Are you saying to yourself, WELL I don't do anything terrible like that? You may not be using illegal drugs to do it, but every time you override feedback from your body that you are tired and pushing past your limitations, you are going into debt with your kidney jing.
Can it be replaced? Not entirely. Jing is like our own personal candle wick. All you can really do is slow down the rate you are using it up. Way down, if you are smart and listen to your body. For each of us, there is an end, of course. We are not immortal.
Chi is the essential energy of the kidney. It is burned out by overuse of adrenals [fight or flight] and lifestyle imbalances. People who become exhausted have weak kidney chi. So do most people who are ill with chronic diseases. Depleting kidney chi weakens the immune system.
The profligate use of Yang [male] energy is responsible for a major part of misuse and abuse of an individual's life force. Here's a rule of nature: Yang energy must protect yin energy, which in return nurtures yang. If you are too busy, don’t get enough rest, do not stop when you reach a breaking point, do not listen to your body, regularly use stimulants to be ‘up,’ when you consistently seek the adrenalin rush because it makes you feel ‘alive,’ you are not protecting your yin and you are using up life force that you may not be able to replace.
From within our bodies, to our relationships, to every corner of the world, the biggest and most obvious imbalance of yin and yang is: Privileging male energy, in any form, over yin – female energy. The most aggressive, fastest person does not always accomplish a task more effectively than a slower, more thoughtful, more yin individual. [It may feel great to have to wind rush past your face, but is that real speed or just a breeze from a fan?]
Yang is great when it ‘absolutely has to be there the next day’ but for most situations, three day mail delivery works just as well. Lots of us feel really good when we are speedy and accomplish a huge amount of work. But there is a big price for the overuse of yang energy. Much better to balance our yin and yang, and enjoy the ride, instead of rushing to each destination as fast as we can. And, above all, it enables us to meet each day, refreshed and energized by a balanced lifestyle, for years to come.
