Aja Ekadashi is a significant observance in the Hindu calendar, celebrated with devotion and reverence by millions of devotees across India and other parts of the world. Falling on the eleventh day (Ekadashi) of the Krishna Paksha (waning phase of the moon) in the month of Bhadrapada, which typically occurs in August or September, Aja Ekadashi is dedicated to Lord Vishnu, one of the principal deities in Hinduism. The name "Aja" is derived from a Sanskrit word meaning "unborn" or "eternal," symbolizing the timeless and infinite nature of Lord Vishnu.

This Ekadashi is particularly revered for its spiritual significance and the belief that observing it can absolve devotees of their sins and lead them towards the path of salvation (moksha).

The legend associated with Aja Ekadashi is rooted in ancient Hindu scriptures, particularly the Brahmavaivarta Purana. According to the legend, King Harishchandra, a noble and just ruler, lost his kingdom, wealth, and family due to a series of unfortunate events. Stricken by grief and despair, he wandered aimlessly until he met the sage Gautama, who advised him to observe the fast of Aja Ekadashi. Following the sage's counsel, King Harishchandra observed the fast with utmost devotion, and as a result, he regained his lost kingdom, wealth, and family. This story underscores the transformative power of Aja Ekadashi and its ability to bring about positive change in one's life.

The observance of Aja Ekadashi involves a strict fast, where devotees abstain from consuming grains, cereals, and certain vegetables. Many choose to observe a nirjala fast, refraining from both food and water, while others may consume fruits and milk. The fast begins at sunrise on the day of Ekadashi and concludes at sunrise the following day, after offering prayers to Lord Vishnu.

Devotees engage in various spiritual activities throughout the day, including reciting Vishnu Sahasranama (a hymn of a thousand names of Lord Vishnu), reading sacred texts, and participating in bhajans (devotional songs) and kirtans (devotional chanting). Visiting Vishnu temples, offering flowers, fruits, and incense, and performing aarti (a ritual of waving lighted lamps) are integral parts of the observance.

The spiritual benefits of observing Aja Ekadashi are manifold. It is believed that the fast purifies the mind and body, enhances spiritual awareness, and fosters a sense of inner peace and contentment. By dedicating the day to Lord Vishnu, devotees seek his divine blessings for prosperity, happiness, and liberation from the cycle of birth and death.

In contemporary times, Aja Ekadashi continues to be celebrated with great enthusiasm and devotion. The festival serves as a reminder of the importance of faith, discipline, and devotion in one's spiritual journey. It also highlights the timeless teachings of Hinduism, emphasizing the values of righteousness, compassion, and the pursuit of spiritual enlightenment.

In conclusion, Aja Ekadashi is a revered festival that holds deep spiritual significance for Hindus worldwide. Its observance is a testament to the enduring power of faith and devotion, offering devotees an opportunity to connect with the divine and seek spiritual growth and fulfillment. As devotees come together to celebrate Aja Ekadashi, they are reminded of the eternal presence of Lord Vishnu and the transformative potential of sincere devotion.
