Q: You sometimes suggest to keep the head in South direction while sleeping. How is it scientifically relevant? Subhash Sagar.
Every principle in Vaastu Shastra is based on our scientific norms.
The magnetic field of the Earth plays an important role while formulating Vaastu suggestions which can significantly influence human life. According to Vaastu norms, one should never keep head towards the north while lying as it obstructs the circulatory system causing irregular sleep, tension, paranoia and other mental problems.
The magnetic fields of the same poles repel each other while the opposite attracts each other, therefore a person should keep the head towards the South or East. This will place your body in consonance with nature. The human body consists of 70 percent blood and blood has iron particles which are controlled by magnetic field.
When we sleep with our head Southwards , the blood circulation is straight.
But when we sleep in the reverse position, it circulates in opposite direction in our body and causes blood disorders, headaches, blood pressure or some complications with regard to blood circulation. Just compare when you travel to Delhi in Shatabadi with your back towards Delhi, when you alight on the platform you feel tired but had you been sitting with your face towards Delhi, while alighting ,you donot feel that much tired .
Q:What are the planets associated with the directions in Vaastu Shastra?
East - Ravi (Sun); South East - Shukra ( Venus); South - Angaraka (Mars); South West - Rahu; West - Shani (Saturn); North West - Chandra (Moon); North - Budha (Mercury); North East - Guru Ketu .
