In plain sight! Observe the position of the hands and the feet in these two images of the Buddha. One hand in the other, the two magnetic polarities connected.
The feet, the same thing!
Perhaps religious iconography is showing us useful info, but we cannot see the wood for the trees. In all my years of research into Sanskrit texts I have never found an explanation as to this, and one often sees old people sitting in this position, maybe their bodies react instinctively.
Obvious, my dear Watson! When you realise that the movement, or current, generated by the flow of blood, the exchange of oxygen, the metabolic, endocrinal and other activity taking place non-stop must be creating a serious magnetic field - even if it is at a very low scale - you have a lot going on but are not doing anything to help it - like recharging that magnetic field using your own tools.
It is perhaps not common knowledge that the human body if a magnetic field, with positive, negative and just one neutral point - the navel. But it is so easy and so immensely beneficial to work on this by adopting a few very simple gestures. Join your hands or interlace your fingers, the polarities will be joined, negative and positive. Now, your feet, just cross them. People with right-handed positive polarity, put your left foot over the right ankle. Right over left ankle for left-handed positive polarity. You will find out after five minutes if you made the wrong choice! You will feel enervated, so change foot. No one, to my knowledge, has ever pointed out that this is just what you are doing when sitting cross-legged in meditation, one hand in the other, but no matter.
With hands and feet joined, sitting at your desk, on the bus, lying down, wherever, you have closed the biomagnetic loop of the body’s field and are recharging for the simple reason you have closed the circuit at the hand and feet. Why do that? The current of the overall movement throughout the body results in an electric charge, measured in millivolts. 10mV and you are at death’s door, at 70 mV – and you will not get higher – you are fighting fit. Most people come in at 25mV, which is weak and the system is probably struggling. What to do? Recharge the magnetic component and that will knock on to the electric!
Another little known fact many people are unaware of is that at menopause a woman's magnetic field is reversed. A painful experience at the best of times but generally resulting in the "flashes" of heat that can drag on for ever. While the recharge will not remove this, it will do a lot to alleviate the discomfort.
