Ashwin: Swamiji, my pranams to you. I heard somewhere that in Ramayana, Ravan's sister once met Sri Rama and wanted to marry him. But Sri Rama asked her to approach Lakshman. After some incident, Mata Sita laughed at her and that made her angry and she tried to attack Mata Sita. Due to that,Lakshman cut off her nose and ears. So Ravan decided to abduct Mata Sita after hearing this incident. Is this episode really happened in Valimiki Ramayana? Also,who is bird Jatayu? How the bird fought with Ravan to prevent the abduction of Mata Sita? Please explain. Thank you very much.
