Vaastu-shastra or Vaastu-science is an ancient Vedic traditional science of building living spaces including temples. Vaastu-shastra considers the spatial orientation of a building with respect to the magnetic grid of the Earth as well as the path of the Sun across the local sky. It also considers the soil type, the local flora and fauna, objects, neighbourhood, gradient of slope, water bodies, underground streams, design of roads and path ways around the grounds. At advanced levels, Vaastu-shastra also accounts for bio-thermal energy grids in the Earth as well as the astrological horoscope of the owners / residents of the living space. This is also known as Astro-Vaastu.
