This slOkam relates to Kalki avathAram. Swamy Desikan recognizes the Lord of Thirumala as “Haya Saadhina:” and celebrates the sahAyam (assistance) given by Dayaa Devi in this tenth and last avathAram of the Lord. This avathAram takes place at the end of Kali Yugam and ushers in the noble Krutha Yugam, where Dharmam stands firmly on its four legs. Swamy Desikan salutes Dayaa Devi as the cause for this avathAram. At the end of Kali Yugam, only sinners will be populating this earth. At that time, Dayaa Devi commands the Lord of ThiruvEnkatam to manifest as Kalki avathAram to lighten the load of the universe. Kalki BhagavAn rides on a white horse, carries a glittering sword, destroys the sinners left and sets the stage for the onset of the noble Krutha Yugam. The sword that Kalki BhagavAn carries is dipped in dayaa to destroy the evil ones and to pave the way through that act to make them attain sathgathy. The Sword in the hand of Kalki is like a cloud. When that sword associates with Dayaa DEvi, it is like the sword drinking the water of compassion. Kalki BhagavAn’s sword-wielding hand is like a roaring wind that pushes the rain-bearing cloud. When the sword swirls in Kalki BhagavAn’s hands,its radiance falls on all directions. That spreading of the lustre of the sword is like the travel of lightning in all directions. That sword's movements drenches the world with the rain of Dayaa. Those who get killed by the sword of the BhagavAn reach sathgathy and are rid of their sins. Through this act of destructon of the sinners, all the SamsAra tApams are banished. After the sword of the BhagavAn destroys Kali dhOshams, the scene is set for the dawn of the most auspicious Krutha Yugam. Dharmam will thrive then. Oh Dayaa DEvi! You make Lord SrinivAsan take the Kalki avathAram thus and assist Him at the end of this Yugam
