While sleeping keep in mind the directions. Head in the direction of East and legs towards West.
If unable head in south direction Head. Never keep your head towards North – It is position of
death.
Inference
There is gravitational force acting between the body and Earth. In a human body,
head is North Pole and legs are South pole. If we sleep with our Head towards
North and legs towards south, a force of repulsion works which increases blood
pressure & increases insomnia. And if place the head towards South and legs towards
North – unlike poles attract & body stretches & brings relaxation, increases
height in children & helps reach a calm state of mind. East/ West is neutral in
gravitation force & either direction are good.
If you are a bramhachari/sadhu: Sleep with your head towards East.
If you are a grahasth: Sleep with your head towards South
