Ramanujacharya was the principal acarya in the Sri sampradaya, one of the four main lines of Vaisnava teachers and disciples. His Vedanta-sutra commentary Sri-bhasya establishes the doctrine known as Visistadvaita, “qualified nondualism.”
It is said that if one observes upavasa on this day then one receives entrance to Visnu’s abode, even though one has not performed the other vratas of the year. Yudhisthira Maharaj said, “Oh Lord of the lords, Sri Krishna, all glories unto You! Oh Master of the universe, You alone are the source of the four types of living entities those born from eggs, those born from perspiration, those born from seeds and those born from embryos. You alone are the root cause of all, Oh Lord, and therefore You are the creator, maintainer and destroyer.
Varahadeva is the boar incarnation Sri Krsna. He assumed the form of a boar to lift the drowning planet earth from the Garbhodaka Ocean with His tusks. The demon Hiryanyaksa had thrown the planet earth into this ocean, but the Lord stabbed the demon with His tusks and saved the earth. After describing the appearance of the white Boar Incarnation that had appeared during the Svayambhuva devastation, Maitreya next described the red Boar Incarnation that had appeared during the Chakshusha devastation. Maitreya related these pastimes to Vidura in the same manner in which he had heard them long ago when Lord Brahma had narrated them to the demigods.
There are various festivities where Lord Krishna’s rasa lila is celebrated – this festival being just one of them. The purnima or full moon of Damodara month is the second full moon of the autumn season, and rasa lila is again celebrated. This second rasa yatra is celebrated more in Bengal, whereas the first one is celebrated more in Vrindavana. On this day one should perform full worship of Radha and Krishna with many flowers, and place them in a rasa mandapa surrounded by the gopis. Sri Krishna Vasant Rasa is similar excepting that it is in the Spring (Vasant), at this time everyone dresses in yellow. On this full moon night the devotees usually leave out pots of sweet rice payasam for the Lord to enjoy during His rasas.
