Om Namo Narayanaya
Where you live decides how you live. I don't want to give you gyaan about how - chi or prana or life force works in bringing good health, joy & prosperity into lives. There are enough & more literatures available on the Internet on how shapes, size, & directions influence events & personal lives. I need not take extra effort about convincing you about this ancient art. The only thing I am aware is - it works & it works perfectly!
