U Thlen is a symbol of greed that is a human heart and greed can make people do thing which is even against the common good people of the and even their own will for the sake of wealth. The Khasi-Pnar believed that they had killed the beast and did away with greed from the heart of the people except from some of the rich families, but that is not so. Our ancestors may have killed the beast, but greed prevails in the heart of the people. It is difficult to satisfy greed because greed knows no bound. We know this because our ancestors have lived with whatever is underneath the ground for ages and live happily on these rolling hills till we start exploiting the minerals.
