The Ādityavāra-vrata-kathā is a popular story in Digambara circles. It shows the good and bad results of observing or not observing the so-called 'Sunday vow'. This is one of the numerous vows – vratas – which a Jain can keep to counteract the misfortunes of life, to acquire merit and diminish the quantity of karma. Observing such a vow means fasting, worshipping and also listening to specific stories. Some vows are connected with a given day of the week.
Jains believe that there are 24 Jinas in each complete cycle of time in the human world. A 'victor' in Sanskrit, a Jina is an enlightened human being who has triumphed over karma and the neverending cycle of births in which the soul is trapped. Also known as a Tīrthaṃkara or 'ford-maker', a Jina teaches the way to achieve liberation.
