Calm in the Doctrine of Buddha
381. The Bhikshu, full of delight, who is calm in the doctrine of Buddha will reach the quiet place (Nirvâna), cessation of natural desires, and happiness.
382. He who, even as a young Bhikshu, applies himself to the doctrine of Buddha, brightens up this world, like the moon when free from clouds.
