The Ancient Science of Sun Worship
Vedic traditions are often deeply intertwined with natural sciences. Chhath Puja is a prime example of an ecological and biological health system disguised as a religious festival.
Solar Refraction
When the Vrati pours milk and water from the Soop, they are instructed to look at the sun through the falling stream. Scientifically, this acts as a prism. The water breaks the sunlight into a spectrum, and absorbing this filtered light through the optic nerve is believed in holistic science to balance the body's energy centers and improve vision.
