Sri Vaishnavism is a branch of Hinduism that focuses on devotion to Lord Vishnu, the preserver and protector of the universe. The teachings of Ramanuja, a prominent saint and philosopher, form the core of this belief system. Sri Vaishnavism has a rich tradition of festivals that are celebrated with great fervor and devotion by its followers.

One of the most important festivals in Sri Vaishnavism is Vaikuntha Ekadashi. It falls on the 11th day of the waxing moon in the month of Margashirsha (December-January). It is believed that on this day, the gates of Vaikuntha, the abode of Lord Vishnu, are open for devotees to enter and attain moksha (liberation). Devotees observe a fast and offer prayers and special rituals to Lord Vishnu to seek his blessings.

Another significant festival is Rama Navami, the birthday of Lord Rama, an incarnation of Lord Vishnu. It is celebrated on the 9th day of the waxing moon in the month of Chaitra (March-April). Devotees offer prayers and perform puja to Lord Rama and recite the Ramayana, the epic story of his life. The festival is also marked by processions and cultural programs depicting the life of Lord Rama.

Janmashtami, the birth anniversary of Lord Krishna, is another important festival in Sri Vaishnavism. It falls on the 8th day of the waning moon in the month of Bhadrapada (August-September). Devotees observe a fast and perform puja to Lord Krishna, who is considered an incarnation of Lord Vishnu. The festival is celebrated with great enthusiasm, with temples adorned with colorful decorations and devotees singing and dancing in praise of Lord Krishna.

Other festivals celebrated in Sri Vaishnavism include Narasimha Jayanti (birthday of Lord Narasimha, an incarnation of Lord Vishnu), Varaha Jayanti (birthday of Lord Varaha, another incarnation of Lord Vishnu), and Deepavali (festival of lights). Each of these festivals has its own significance and is celebrated with rituals, prayers, and offerings to Lord Vishnu.

In conclusion, the festivals celebrated in Sri Vaishnavism are an integral part of its rich tradition and serve as a means for devotees to express their devotion and seek the blessings of Lord Vishnu. These festivals not only bring joy and happiness but also serve as a reminder of the teachings of Ramanuja and the ultimate goal of attaining moksha through devotion to Lord Vishnu.
