English: Poireiton Khunthok (also known as Poireiton Khunthokpa) — c. 3rd century CE — A literary treasure of the Classical Meitei language of Ancient Kangleipak civilization

“The Poireiton Khunthokpa, is the most conspicuous one of all pre-Garibniwaz manuscripts. From a linguistic point of review, it seems to be much earlier than any of the books yet come under our view. Circumstantial and other incidental evidences would confirm that the book might have been of the time of the third century A. D. It describes the colonization of the valley by a band of prople from the land of Death under Poireiton. They first established their colony near the Langol Hill; probably the vast area between the Koubru Hill and the Langol Hill was their kingdom.”
