Ekadashi, according to Hindu calendar, is the eleventh day of the month. Vaikuntha Ekadashi, however, is the most significant of all.
It is said that worshipping Lord Vishnu on this day is very auspicious and beneficial. It is because, according to Hindu belief, the gates of Lord Vishnu’s abode, Vaikuntha, are opened for all on this day. So those who observe a fast on this day are likely to attain salvation. After their death, these people exit the cycle of birth and death, and go straight to heaven, where reside all the gods.
Vaikuntha Ekadashi is also known as Mukkotti Ekadashi according to Tamil Panchang. In Kerala, it is famous as Swarga Vathil Ekadashi. The large festivities and celebrations can be observed on this day in Tirupati Balaji temple.
This day is also known as Gita Jayanti and Mokshada Ekadashi. The latter is for the same reason as above –people attain moksha or salvation by fasting on this day. The former name comes from the mythological context of Mahabharata.
It was on this day that Lord Krishna
(who is an incarnation of Lord Vishnu
) gave the lesson of Srimad Bhagavad Gita
, during the war of Kurukshetra
