Special care should be taken of the health of the inhabitants, which will depend chiefly on the healthiness of the locality and of the quarter to which they are exposed, and secondly on the use of pure water; this latter point is by no means a secondary consideration. For the elements which we use the most and oftenest for the support of the body contribute most to health, and among those are water and air. Wherefore, in all wise states, if there is want of pure water, and the supply is not all equally good, the drinking water ought to be separated from that which is used for other purposes.
Even if a fool lived with a wise man all his life, he would still not recognise the truth, like a wooden spoon cannot recognise the flavour of the soup.
By three things the wise person may be known. What three? He sees a shortcoming as it is. When he sees it, he tries to correct it. And when another acknowledges a shortcoming, the wise one forgives it as he should.
Still others commit all sorts of evil deeds, claiming karma doesn't exist. They erroneously maintain that since everything is empty, committing evil isn't wrong. Such persons fall into a hell of endless darkness with no hope of release. Those who are wise hold no such conception.
All that glitters is not gold; Often have you heard that told: Many a man his life has sold But my outside to behold: Gilded tombs do worms enfold Had you been as wise as bold, Your in limbs, in judgment old, Your answer had not been in'scroll'd Fare you well: your suit is cold.' Cold, indeed, and labour lost: Then, farewell, heat and welcome, frost!
So the state founded on natural principles is wise as a whole in virtue of the knowledge inherent in its smallest constituent class, which exercises authority over the rest. And the smallest class is the one which naturally possesses that form of knowledge which alone of all others deserves the title of wisdom.
Foolish, selfish people are always thinking of themselves and the result is always negative. Wise persons think of others, helping them as much as they can, and the result is happiness. Love and compassion are beneficial both for you and others. Through your kindness to others, your mind and heart will open to peace.
Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.
