Ekadasi is a significant fasting day in the Hindu calendar, observed twice a month on the 11th day of each lunar fortnight. It is dedicated to Lord Vishnu, one of the principal deities in Hinduism, and is believed to bring spiritual benefits and purification. Devotees often abstain from grains and certain foods, focusing on prayer and meditation. The practice of Ekadasi is rooted in ancient scriptures, with many followers believing it helps in attaining spiritual growth and liberation. Each Ekadasi has its own significance and rituals, making it an important aspect of Hindu religious life and devotion.
