When the spine is erect, making a ninety-degree angle with the earth, your body expends the least energy possible. If you are leaning towards the left or towards the front, then your body starts spending more energy, because the gravitation starts pulling you downwards and you have to keep yourself, you have to hold yourself so that you don’t fall. This is expenditure. An erect spine was found to need the least spending of energy. Then sitting with your hands together in the lap is also very very useful for low-energy people, because when both the hands are touching each other, your body electricity starts moving in a circle. It does not go out of your body; it becomes an inner circle, the energy moves inside you.
You must know that energy is always released through the fingers, energy is never released from round-shaped things. For example, your head cannot release energy, it contains it. Energy is released through the fingers, the toes of the feet and the hands. In a certain yoga posture the feet are together, so one foot releases energy and it enters into the other foot; one hand releases energy and it enters into the other hand. You go on taking your own energy, you become an inner circle of energy. It is very resting, it is very relaxing.
The yoga posture is the most relaxed posture possible. It is more relaxing than even sleep, because when you are asleep your whole body is being pulled by gravitation. When you are horizontal it is relaxing in a totally different way. It is relaxing because it brings you back to the ancient days when man was an animal, horizontal. It is relaxing because it is regressive; it helps you to become an animal again. That’s why in a lying posture you cannot think clearly, it becomes difficult to think. Try it. You can dream easily but you cannot think easily; for thinking you have to sit. The more erect you sit, the better is the possibility to think.
