Rama as king affirmed - " To make the people happy, I could give up anything - love, pleasure and even Sita."So, when whispers doubting Sita's chastity in Ravana's captivity, came to Rama he sent away the pregnant Sita. She was given refuge by sage Valmiki, author of the 'Ramayana'. There she gave birth to twin sons who were named Kush and Luv. Valmiki trained them into martial arts as well as recital of Ramayana.Rama pined for Sita, even as he performed the royal horse sacrifice. The horse was trotted abroad with Lakshmana as defender.Kush and Luv were revealed as sons of Sita, to Lakshmana in their winning encounter with him. The twin sons and Sita appeared before Rama and Sita finally returned to mother Earth. The story is narrated here from the 8th century playwright Bhavabhuti's Sanskrit play called "The Later Life of Rama". - from Amzon
