Jai Sri Ram,
O Girija, Listen, Rama is beyond grasp of intellect, mind and speech, such is my conviction, tell you the reason as I understand it, Vedas and Puranas have related this divine subject in their their own light, whenever virtues decline and vile and haughty demons multiply, when Brahmanas, Cows, gods and earth are in trouble, the gracious lord Sri Hari takes various forms and transcends to relieves the distress of the virtuous,
Killing the demons and reinstate the gods, preserve the bounds of propriety fixed bt the Vedas is the motive of Rama's descent, moreover for the sake of devotees that compassionate Lord bodied himself forth, Infinite is truth his incarnation in the form of Rama so is the trait to relate the truth of this unique reality,
Refer you two births in brief, please perceive it attentively, O wise Girija, There had been two gate keepers of the Lord named Jaya and Vijaya, due to curse of Brahman they attains to the form of demons that Hiranykasupa and Hiranyaksha, become known throughout the world, lord assume the form of a Boar and Man-lion to liberate them from that life of curse they had been living,
Strange phenomena of Maya follows them and though they slain by the lord in direct flix, they remained failed to attain liberation as the curse was for three births, they again embodied as Ravana and Kumbhakarana and Lord to revisit them suitably to fix their past curse, in an another aspect once Lord himself bear the curse from a chaste consort of demon Jallandhar, truth of her chaste lady was his infallible strength and lord cross that barrier and falls prey to her curse to suffer and so many alike things could have been the reason of descend of Lord Rama,
Jai Siya Ram
