Kakabhushundi (काकभुशुण्डि) is an immortal sage with the body of a crow. The ‘Kaka’ part of his name just means ‘crow’; his actual name is Bhushundi. He is one of the greatest Bhaktas of Lord Rama. He learned Rama Bhakti from his Guru, Lomasa Muni, while in the form of a crow, and such was his devotion that Rama granted him immortality and the Siddhi to travel through time or stand outside of time, but only as an observer. With this Siddhi he has watched the events of the Ramayana play out eleven times and the Mahabharata sixteen times, each with different results as they occurred somewhat differently in different Kalpas. He could take any form he wished, but prefers to remain a crow, since it was as a crow that he learned about Rama.
Bhushundi was the first narrator of the Ramayana, before even Valmiki; he told the story to Garuda.
Due to his immortality he is counted among the Chiranjivis, or truly immortal beings still living in their original physical body.
