who tried to stop ravana from kidnapping sita
Jatayu In the epic Ramayana when Jatayu sees Ravana abducting Sita, he tries to rescue Sita from Ravana. Jatayu fought valiantly with Ravana, but as he was very old Ravana soon got the better of him.
Sanghamitta Saṅghamittā (Saṅghamitrā in Sanskrit) was the eldest daughter of Emperor Ashoka (304 BC – 232 BC) and his first wife, Devi. Together with her brother Mahinda, she entered an order of Buddhist monks. The two siblings later went to Sri Lanka to spread the teachings of Buddha at the request of King Devanampiya Tissa (250 BC – 210 BC) who was a contemporary of Ashoka. Ashoka was initially reluctant to send his daughter on an overseas mission. However, because of the insistence of Sangamitra herself, he finally agreed. She was sent to Sri Lanka together with several other nuns to start the nun-lineage of Bhikkhunis (a fully ordained female Buddhist monastic) at the request of King Tissa to ordain queen Anulā and other women of Tissa's court at Anuradhapura who desired to be ordained as nuns after Mahindra converted them to Buddhism.[1][2][3][4][5]
