Varuthini Ekadashi falls during the Krishna Paksha of Vaishakha (Madhusudana) month. The word 'Varuthini' is derived from 'Varutha', which means an armored shield of protection. Observing this holy fast shields the devotee from all physical dangers, spiritual falls, and guarantees an auspicious rebirth.
In ancient scriptures, Lord Krishna explained the glory of this day to King Yudhisthira. He stated that observing Varuthini Ekadashi provides the same spiritual benefit as donating a mountain of gold or performing countless horse sacrifices. It has the special power to cure severe physical ailments and transform misfortune into luck.
The story refers to ancient King Mandhata, who achieved absolute spiritual liberation by observing this fast. Another legend tells of King Dhundhumara, who was cured of a terrible, incurable disease and freed from his tormenting sins simply by dedicated fasting on this day. It is also believed that donating sesame seeds, water, and food on this day brings supreme peace.
Thus, Varuthini Ekadashi is highly revered by Vaishnavas as the day of ultimate divine protection. It ensures that any devotee who fasts on this day is shielded by Lord Madhusudana's personal Sudarshana Chakra, keeping them safe in this life and the next.
