Oh DayA Devi! A chEthanan, who gets to ThirumalA must be a BhAgyasAli. ThatbhAgyam is gained through Your anugraham. Suppose such a man, who has arrived at Thirumala dies, two words (Raksha Maam) come out of his mouth. DayA DEvi! You are responsible for that happening as well. The chEthanan did not utter these two words with deliberation. His limbs are in a state of diminished power and he is in a state of stupor. Inspite of that pitiable state, these two words come out of his mouth. The dying chEthanam receives comfort now. The result is that Your Lord with His Devis appear before the chEthanam during his last moments generating the sound of OmkAram. The meaning of OmkAram is the pledge that He will perform the act requested. That OmkAra dhvani becomes the karNa manthram for the dying jeevan. Why does He engage in this act ?It is because of His awareness that performing that upakAram will please Your (DayA DEvi’s) heart and that would lead to Your merciful glances falling on Him. Thus casting the body at Thirumala leads to Moksham with Your help.
