"Celebrated sage Markandeya tells us that man becomes learned when he sleeps with his head to the east. It appears that the thermal energy helps in creating a comfortable environment when one sleeps with the head placed in the east. When the head is placed in the west, the flow of this energy creates possible disturbance to sleep resulting in some distress and confused thinking."

"Sage Markendaya also tells us that man acquires strength and longevity by sleeping with his head to the south. When the current of thermal electricity passes from the east to the west, the earth becomes magnetized and its geographical North Pole, which is to the right hand side of the direction of current, becomes the magnetic north pole and its geographical South Pole being on the left-hand side of the same current, becomes the magnetic South Pole. It has been proved by experiments that the human body is capable of being magnetized and that it contains a large percentage of iron in the blood that circulates all through the body. As the feet are always in constant touch of the huge magnet (the earth), which exhibits the properties of north polarity, south polarity is induced in our feet and consequently north polarity is induced in the head. The body enjoys good health because of the natural polarity being unaltered. On the other hand when the head is placed to the north, the natural polarity gets altered and possibly affects the health."
