Devotees observe fast on the day of Aja Ekadashi in honour of Lord Vishnu.
The observer of this Vrat should also eat ‘simple’ food even a day before, that is on ‘Dashami’ (10th day) to free the mind from all negativities. The observer of the Aja Ekadashi Vrat must wake up before sunrise and then take a bath with mud and Sesame seeds.
The place for puja must be cleaned. A little bit of rice is kept at a cleansed location, over which the sanctified ‘Kalash’ is placed. The top of this Kalash is covered with red cloth, and an idol of Lord Vishnu is placed atop it. The devotees worship the idol of Lord Vishnu with flowers, fruits, and other puja essentials. A ‘ghee’ lamp is lit in front of the idol. The devotees should refrain from eating all through the day, even a drop of water is not allowed. Young children and ill people are allowed to eat fruits during Vrat.
All kinds of grains and rice should be avoided on this day. The devotees read sacred books like ‘Vishnu Sahastranam’ and ‘Bhagwad Geeta.’ The observer should also keep night vigil and spend the time worshiping and meditating. The observer of Aja Ekadashi Vrat needs to also follow the principles of ‘Brahmacharya.’ The fast is broken on the day of ‘Dwadashi’ (12th day), after offering food to a Brahmin. One must abstain from eating brinjal on ‘Dwadashi.’
