Another reason for observing Vratas is the belief that they are a form of sorry, self-correction, penance and expiatory (prāyaścitta). Vratas are discussed as a means to prāyaścitta in Dharmasastra texts. Many prāyaścitta vratas in these texts suggest it include the feeding of "Brahmins, blind, poor and helpless", as well as other acts of charity. However, a Vrata can consist of many different activities. Other examples of Vrata activity include fasting, burning incense sticks, prayers before a deity, meditating and such activities. The śmrtis go into great detail on the subject of vratas, discussing even the details pertaining to what type of flowers should be used in worship.
