Ekadasi is
dedicated to Lord Vishnu and is observed on the 11th day of waning and waxing
phase of moon in traditional Hindu calendar. It is believed that by fasting on
Putrada Ekadasi one is relieved of all the sins committed. The greatness of
this Ekadasi was explained to Yudhishtira by Lord Krishna and is found in the
Bhavisyotara Purana.
There is a
popular belief that married couples without children will be blessed with
children if they observe Putrada Ekadasi.
Most Vishnu
devotees fast on the day and some devotees do not sleep. Those people observing
partial fasting abstain from food made of rice.
