“Leaving behind son and wife, and father and mother, and wealth and grain, and relatives, and sensual pleasures to the limit, one should wander solitary as a rhinoceros horn.
'This is an attachment; here there is little happiness, and little satisfaction; here there is very much misery; this is a hook.' Knowing this, a thoughtful man should wander solitary as a rhinoceros horn.
Having torn one's fetters asunder, like a fish breaking a net in the water, not returning, like a fire not going back to what is already burned, one should wander solitary as a rhinoceros horn.”

§ 60-62
