Vrat is essentially fasting and is threaded with several rituals and customs of the Hindu Culture. Vrat means a vow not to touch eatables and sometimes even water for entire tenure of the custom or a festival that a person chooses to observe. A vrat is kept by devotees to please the Gods and Goddesses with their devotion. Besides the benefit of fasting, vrat is a determined effort. It displays the resolve of a person and the will to govern natural instincts.
When the followers of gods and goddesses fast, they do not eat cereals, wheat and spices. Intake of several vegetables is also prohibited during vrat or Upvas. Fresh fruits, dry fruits, nuts and milk products are among the most preferred eatables consumed while fasting or when breaking a fast. Some vrats are more stringent than others and extend beyond a day and sometimes last for many days. There are devotees who don’t consume even water during the period of fasting to appease their gods.
