Sun is the Lord of Intellect. After giving oblations to Sun, Suryanamaskar is done. Performing Suryanamaskar is very beneficial for circulatory, respiratory & digestive system. Apart from physical flexibility and mental agility, it increases memory power and thinking power. Gurukul students are benefited by doing Sun worship.
It is mentioned in the Rigveda that not only Sun illuminates the whole world but its rays have unparalleled power to increase immunity & remove health problems. Sun's light rays destroy the weakness & ailments of the Heart. (RV 1.50.11)
