Vaikunta Ekadashi is one of the most important Ekadasis.Ekadashi is an auspicious day dedicated to Bhagvan Srihari Vishnu and falls on the eleventh day of every lunar fortnight in traditional Hindu calendar. In 2015, the date of Vaikunta Ekadasi is January 1. Swarga Vasal or or Paramapada opening is at 4:30 AM on January 1, 2015. Please note that in United States and UK it is marked on December 31, 2014.Vaikuntha Ekadasi is observed in the Margali Month (Margazhi Masam) as per Tamil Calendar and in Pushya month as per Telugu Calendar.
Fasting, keep vigil at night and passing through the Vaikunta Dwaram are the important auspicious activities on the day.The most important ritual on the day in temples is the opening of the Vaikunta Dwaram or Paramapada Vasal door in Vishnu Temples. This door is only opened on the Vaikunta Ekadasi day and devotees are allowed to pass through it. Symbolically the door leads to the Vaikunta – abode of Vishnu.
Like all Ekadasi days, devotees fast on this day and observe vigil the whole night. Some people indulge in meditation, Japa and singing of Hari Kirtan. It is believed that a partial or total abstinence from food on Ekadasi is rewarded with bliss. Ekadashi observance cleans our body and the digestive organs get much needed rest. The fast is broken on the next day (Dwadashi) after taking bath. Offer prayers to Lord Vishnu by lighting a lamp and then you can break the fast.
