Ravivar Vrat in Hindu Religion is dedicated to Surya, the Sun God in Hinduism. The popular belief is that observing Sunday fasting will help in early cure of skin diseases. Long ago there lived a pious old lady who performed Ravivar Vrat without fail. She used to get up early on Sunday morning, plaster her house with cow dung and then offer food to Surya. The old lady led a very happy life with the blessing of Sun God. The old lady did not own a cow so she used to collect cow dung from her neighbor’s cowshed. The neighbor lady was jealous of the happy life of the old lady. So to stop the Ravivar fasting of the old lady, she started tying the cow inside her house. The next Ravivar, the old lady could not offer her prayers as there was no cow dung to plaster the place. So she did not cook any food and went hungry the whole day. The sun god appeared in her dream in the night and blessed her with a beautiful cow and a calf. In morning, the old lady found the same cow and calf
