Perhaps the most amazing unknown fact from The Ramayana. Tara (wife of Bali) cursed Rama so that he will soon lose Sita after he regains her. She also declared that Sita will return to the earth. This happened after Rama killed Bali when he was having a duel with Sugriva. Tara additionally cursed Rama that in his next birth, he will be killed by Bali. (Shri Krishna and the hunter).
