Amalaki Ekadashi, also known as Phalgun Krishna Ekadashi, is a significant Hindu festival celebrated on the eleventh day of the waxing moon in the month of Phalgun (February-March). This auspicious day holds great importance in the Hindu culture as it is believed to be the day when Lord Vishnu awakened after a long slumber.

The festival derives its name from the Indian gooseberry tree, also known as Amalaki. It is believed that worshipping the tree and consuming its fruit on this day can help in the purification of the body and mind, and bring good health and prosperity.

According to Hindu mythology, it is said that King Mandhata was once visited by the sage Angira, who advised him to observe the Amalaki Ekadashi fast to gain prosperity and fulfillment of wishes. The king observed the fast and was able to regain his lost kingdom and attain happiness.

On this day, devotees observe a fast and worship Lord Vishnu to seek his blessings. The fast is believed to help in purifying the soul and bringing good fortune. Devotees offer prayers, chant mantras and hymns, and perform aarti to seek the blessings of Lord Vishnu.

It is also believed that donating food, clothes, and other items to the needy on this day can help in accumulating good karma and bring happiness and prosperity.

The festival is celebrated with great enthusiasm and zeal, especially in the northern parts of India. People decorate their houses with flowers and lights and prepare traditional delicacies like amla murabba, amla pickle, and amla candy.
