Vasthu sastra is an ancient architecture. It is a part of Jyotisha which we have inherited from ancient vedic wisdom. It is a science that derives its roots from the SUN, the source of all energy and life. It takes the Panchaboothams of Earth, Sky, Water, Fire and Air into consideration. Construction according to principles of vaasthu sastra brings happiness, peace of mind and prosperity to inhabitants.
From Bhagwat Gita
"They Who perform their work offering all results to me, who hold their hearts and minds steadfast in me in whatever they do, who worship their work, to them I offer the platform. Doubt it not that they will inexorably reach the top. "
- Bhagwat Gita 12.6/12.8
