Jai Sri Ram,
Even though slain by the lord, the two brothers did not attain liberation, for the Brahmanas had doomed them to three births, it was on their account that the lovers of the devotees bodied themselves forth on one occasion, in that birth Kashyapa and Aditi were his parents, who were known by the names of Dasaratha and Kausalya respectively,
This was how in one kalpa the lord descended from heaven and performed purifying deeds on earth, in another Kalpa all the gods were worsted in their conflict with the demon Jalandhara, seeing their distress Sambhu wages war against him, which knew no end, but the demon, who possessed a great might could not be killed in spite of his best efforts,
The wife of the demon chief was a most virtuous lady, armed by her strength of character the demon could not be conquered even by the vanquisher of Tripura, by the stratagem the lord broke her vow of chastity and accompanied the purpose of the gods when the lady discovered the trick, she cursed him in her wrath,
The supportive and gracious Lord accepted her curse, it was this Jalandhar who was reborn as Ravana in this latter Kalpa, killing him in battle Sri Rama conferred on him the supreme state, this was the reason why Rama assumed a human form in one particular birth, Hark, O Bhardwaj, the story of each birth of lord has been an excuse of his birth in a votary of God Vishnu and enlightened soul too, wherefore did the sage pronounce a curse, What offense had lord committed against him, tell me the whole story, O slayer of demon Tripura, it is very strange that the sage should have fallen prey to delusion,
May Lord bless all,
Thanks, please
