Which are the directions one should sleep -like keeping head in North/South/East/West ?

Answer : When in your own home, keep head towards east while sleeping. Mind, body, concious and sub-concious all are in a relaxed condition.

While travelling and during outstation stay, keep your head towards west – Mind and concious relaxed but body and sub-concious stays alert.

Towards north, mind relaxed to some extent,  but concious, sub-concious and body get disturbed because of the equotarial magnetic pulls.

If a person keeps his/her towards south regularly, the person looses memory power quickly and might feel very weak in normal activities.

Never to keep head towards north or south while sleeping, as the North/South pole magnetic path disturbs the brain and cervical parts that gradually gets damaged.  If a person keeps regularly head towards south while sleeping, then the earths rotation pulls the current towards north, that disturbs the intricate functional of the body parts. Gradually one feels older even before he attain his actual older age if a person keeps head towards north or south while sleeping!
