The Buddha's Way of Virtue, by W.D.C Wagiswara and K.J. Saunders, , at sacred-texts.com
The elephant is the symbol in Buddhism of endurance and solitary strength.
320. I will endure abuse as the elephant endures the arrow in the battle: evil is the crowd.
321. Men lead the tamed elephant into battle; upon his back the king rides: he who is tamed and endures abuse patiently is praised of men.
322. Noble are the tamed mules; noble the blood-horses of Sindh, and the great elephants of war: better is he who has tamed himself.
323. Not by bridling them will one journey to the unknown shore (Nirvāna), but by bridling himself.
324. Dhānapālako, the great elephant, is hard to control in the time of rut: he will not taste his food in captivity, but longs after the elephant-grove.
325. If one becomes a sluggard or a glutton, rolling over in gross sleep like a stall-fed hog,
again and again does he come to the womb, the foolish one!
326. This mind of mine would wander in days of old whither desire and lust and caprice led it: now will I control it as a mahout controls the elephant in rut.
327. Be ye zealous: guard your thoughts. As an elephant sunk in the mud extricate yourselves from the clutches of evil.
328. If you can find a dutiful friend to go with you, a righteous and prudent man not caring for hardships, go with him deliberately.
329. If you cannot find such a one, travel alone as a king leaving a conquered realm, or as the elephant in the jungle.
330. It is better to be alone; there is no companionship with a fool: travel alone and sin not, forgetting care as the elephant in the jungle.
331. Good are companions in time of need; contentment with thy lot is good; at the hour of death, merit is a good friend, and good is the leaving of all sorrow.
332. Good is reverence for mother and father: good, too, reverence for recluses and sages.
333. Good is lifelong righteousness; and rooted faith is good: good is the getting of wisdom, and good the avoiding of sin.
