They were talking like this, "There will be a king named Ram on this earth. His wife's name will be Sita. He will rule for 11,000 years along with Sita. Blessed are Ram and Janaki who will enjoy each others company."
Sita got curious hearing Her name and Her future, so She thought, "Let me ask something more about my future." So She asked Her friends to catch those birds. Her friends brought those birds to Her.
Sita said to them - "Don't be afraid at all, you are very beautiful. Tell me, who are you and where have you come from? Who is this Ram and who is this Sita? How do you know about them? Tell me everything."
The birds said - "There is a Rishi named Valmeeki who is regarded very high. We live in his Aashram only. He has written a big book named "Ramayan" which seems very dear to him. He always reads the couplets of that book. We have heard it in full and since we hear it always, we also remember it. Now you listen to about Ram, and Sita and the events about their lives. By the help of Rishyashring Muni's Putreshti Yagya, Vishnu will appear in four forms - Ram, Lakshman, Bharat and Shatrughn. Ram will come to Mithila along with His brother Lakshman and Vishwaamitra. He will break the bow which will be very difficult to break, and marry the beautiful daughter of Janak - Sita. We have told you everything, now you please free us."
Sita again asked them - "Where will be Raam? Whose son He will be? How will He look like?"
Hearing this the she-parrot knew that She was Sita. She fell onto Her feet and said
she parrot- "He will be like lotus bud. In fact who has hundred mouths, even he cannot describe His beauty, who am I to describe it? Blessed is Sita who will enjoy with Ram for thousands of years. But who are you? What is your name who is asking about Ram with so much curiosity?"
Sita said telling them about Her birth - "Whoever Sita you are talking about, She is me. When Ram will come here and accept me, then only I will free you. Now you live in my house and eat sweet things."
Hearing this the she-parrot said - "Janaki, We are the birds of forests, we live on trees and wander around. How we will be happy in your house? I am pregnant. Let me go and deliver my babies, then I will come back to you."
But Sita didn't free her. He-parrot requested Her to free his wife but Sita told him to go leaving his wife there only. Hearing this the he-parrot got sad and said
he parrot- "Whatever Yogee say, that is correct, that one should be silent and should not say anything to anybody, otherwise he is bound to his words. If we did not talk like this here, then why we should have been caught here. It would have been better if we were quiet."
He again requested Sita to free his wife but She didn't free her. Then the she-parrot gave Her Shaap - "As you are separating me from my husband at the time of my pregnancy, in the same way you will also be separated from Ram at the time of your pregnancy." And she died with sorrow of the separation of her husband. Since she died talking about Ram, a Divine Vimaan came to take her. After the death of his wife, the parrot said
he parrot- "I will take birth in Ayodhya and Ram will separate you by my words only." And off he flew.
Because he insulted Sita in sorrow and anger, he was born as a washerman. Whoever dies saying bad words about great people, even if he is the highest Brahman, he is born in lower class beings, that is why he was born as a washerman. Because of that washerman, Sita got separated from Ram at the time of Her pregnancy.
