Vaastu - Vastu Shastra - Sacred Vedic iinterior

The Oldest interior Philosophy
For over five thousand years, sacred architecture has been practiced in India. The oral traditions were written in Sanskrit mantras and called "Vastu Shastra." Practitioners design and build living environments in harmony with the physical and metaphysical forces/energies of the cosmos such as the gravitational, electromagnetic, supernatural, and metaphysical.

Some similarities sound like the more popular Feng Shui. However, even though Vastu harmonizes the flow of energy, called Life-Force or Prana in Sanskrit, (similar to Chi in Chinese), through the house, Vastu and Feng Shui differ in the placement and directions for objects, rooms, and materials.

Interesting tidbit: I did a map of our home to rate it according to Vastu principles and our home got the highest rating!

Feng Shui Practice

Although some designers claim that Feng Shui is based on superstition, many of the Feng Shui principles can help to make a home that "flows" well. Feng Shui comes from the Chinese art or practice of positioning objects, especially graves, buildings, and furniture, based on a belief in patterns of yin and yang and the flow of chi that have positive and negative effects.

I like many of the Feng Shui decorating ideas, like using mirrors next to my desk so I can see behind me. However, I could find no scientific reason to not use mirrors in bedrooms.
