Hold it in Thoroughly
324. The elephant called Dhanapâlaka, his temples running with sap, and difficult to hold, does not eat a morsel when bound; the elephant longs for the elephant grove.
325. If a man becomes fat and a great eater, if he is sleepy and rolls himself about, that fool, like a hog fed on wash, is born again and again.
326. This mind of mine went formerly wandering about as it liked, as it listed, as it pleased; but I shall now hold it in thoroughly, as the rider who holds the hook holds in the furious elephant.
327. Be not thoughtless, watch your thoughts! Draw yourself out of the evil way, like an elephant sunk in mud.
