The wise say that it is not an iron, wooden or fiber fetter which is a strong one, but the besotted hankering after trinkets, children and wives, that, say the wise, is the strong fetter. It drags one down, and loose as it feels, it is hard to break. Breaking this fetter, people renounce the world, free from longing and abandoning sensuality.
If you cannot find a good companion to walk with, walk alone, like an elephant roaming the jungle. It is better to be alone than to be with those who will hinder your progress.
If a man's thoughts are muddy, If he is reckless and full of deceit, How can he wear the yellow robe? Whoever is master of his own nature, Bright, clear and true, He may indeed wear the yellow robe.

Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.
Those who recognize the existence of suffering, its cause, its remedy, and its cessation, have fathomed the four noble truths. They will walk in the right path.
