Vrat refers to religious vows or observances in Hinduism involving restrictions on food and behavior. Vrats can be undertaken for religious purposes, to celebrate cultural traditions, or to seek divine help. They typically involve fasting, purity practices, and rituals focused on deities. Vrats can vary in duration from a day to a year and involve different levels of austerity. The goal is spiritual discipline and purification of mind and body to gain worldly and otherworldly benefits as well as express religious devotion.
