Aditya Shanti Vrata is observed when Hasta nakshatra falls on a Sunday. The main ritual on the day is offering 28 or 108 Ark plant sticks to a yajna (fire). A murti or painting of Surya is kept in front of the fire pit. Honey and ghee are also offered in the homa.
The Vrata is to be repeated seven times when Hasta nakshatra
coincides on Sunday.
The popular belief is that a person performing the ritual
will have horoscope related problems solved with a strong Surya Navgraha. The
vrata is also performed for finding a solution to skin related diseases. It is
also believed that observing it will help in achieving peace and prosperity.
