fasts and vrats
What is Purnima vrat and which deities are worshipped on full moon fasts?
What Purnima vrat is
Purnima means full moon. A Purnima vrat is a fast or spiritual practice done on the full moon day. The word vrat can mean a full fast with no food, a partial fast, or simply a day of prayer and discipline. What people actually do varies widely—some eat only fruit or milk, some skip one meal, some eat nothing until evening, and some simply avoid meat and onion while keeping normal meals light. The practice is seen as a way to mark the full moon as a sacred time and to focus the mind on spiritual practice.
Which deities are worshipped
The deity worshipped on Purnima depends on the month and the family's tradition. Satyanarayan puja, a worship of Vishnu, is one of the most common Purnima practices. Many people also worship Shiva on the full moon, especially in certain months. The moon itself, called Chandra, is worshipped in some households and regions. In Bengal, Kojagiri Purnima in autumn is celebrated with worship and sweets made from new rice. In Maharashtra, the same day has its own customs. Other months have their own Purnima observances tied to different deities and stories. The tradition is flexible—a person or family may follow one main practice or observe several depending on which full moons matter most to them.
Where it comes from
The full moon has held spiritual meaning in Hindu tradition for thousands of years. It is seen as a time when the mind is naturally clearer and the body's energies are heightened. Many important events in Hindu stories and the lives of deities are said to have happened on full moon days. This is why different Purnimas through the year are linked to different gods and stories, and why fasting and worship on these days became a natural part of practice.
Today
Purnima vrat is still widely kept in India and in Hindu communities around the world. In cities and abroad, people often keep it in simpler ways—a lighter meal, a prayer at home, or a visit to a temple. Some families keep the full fast, others keep it as a day of vegetarian eating and extra prayer. Many people do Satyanarayan puja on Purnima, inviting family and friends. The practice adapts to modern life while keeping its spiritual meaning. Whether and how someone observes it is a personal choice that varies by family, region, and what feels right to the person.
