honest, but not judgmentalStrong, but not injurious to othersStraightforward, but not recklessBright, but not blinding.59In leading people and serving HeavenThere is nothing better than moderation.In moderation, one is already following the Tao.When one follows the Tao, great goodness is abundant.When great goodness is in abundance,There is nothing that cannot be overcome.When there is nothing that cannot be overcomeThen there are no limits.Having no limits, one can certainly govern a country.If you know the countrys Mother, you will long endure.I call this having deep roots and a firm stalk.This is the Way of long life and great insight.60Govern a big country as you would fry a smal fish.Approach the world with the Tao and evi will have no power.Not that evi has no power, but it will not harm people.Not that evi is not harmful,But the Sage is dedicated to not harming people-even evi people.When no one hurts another,All will eventually return to the good.61A great country is like a low-lying lake where many rivers converge;A foca point for the Earth, the feminine Spirit of the World.The female always overcomes the male by stillness.Stillness is the lowest position.Therefore a big country, By placing itself below a smaller countryWil win the smaller country.And a smal country, By placing itself below a larger countryWil gain the large country.Therefore, by being humble, one gainsAnd the other, being humble already, also gains.A great country needs to embrace the lowly.The smal country needs to serve others.Thus, both needs are satisfiedAnd each gets what it wants.Remember, the great country should always humble itself.62The Tao is the bosom of the UniverseIt is the good persons treasureAnd the bad persons refuge.Flattery may buy ones positionAnd good deeds can win people overBut if ones heart is not pureThat is All the more reason to cling to the Tao!Therefore when a king is coronated,Crowned in ceremony,Presented with gifts of rare value, And escorted in luxury,All these things pale when compared to the humble gift of the Tao,offered in silence.Why did the Sages of old value the Tao so much?Because, when you seek, you findAnd when you sin, you are forgiven.That is why the Tao is the greatest treasure of the Universe.63Do without doing.Work without forcing.Taste without seasonings.Recognize the Great in the small,And the many in the few.Repay hatred with kindness.Dea with the difficult while it is stil easy.Begin great works while they are small.Certainly the Earth does difficult work with ease,And accomplishes great affairs from smal beginnings.So, the Sage, by not striving for greatness,Achieves greatness.A person who makes promises lightlyIs not regarded as trustworthy.lIf you think everything is easy,You will find only difficulty.That is why the Sage considers All things difficultAnd finds nothing too difficult in the end.64What is at rest is easy to maintain.What has not yet happened is easy to plan.That which is fragile is easily shatteredThat which is tiny is easily scattered.Correct problems before they occur.Intervene before chaos erupts.A tree too big around to hug is produced from a tiny sprout.A nine-story tower begins with a mound of dirt.A thousand-mile journey begins with your own two feet.Whoever tries will fail.Whoever clutches, loses.Therefore the Sage, not trying, cannot failNot clutching, she cannot lose.When people try,They usually fail just on the brink of success.If one is as cautious at the outset as at the end,One cannot fail.Therefore the Sage desires nothing so muchas to be desireless.She does not value rare and expensive goods.She unlearns what she was once taughtAnd helps the people regain what they have lost;To help every being assume its natura way of being,And not dare to force anything.65In ancient times those who followed the TaoDid not try to educate the people.They chose to let them be.The reason people become hard to governIs that they think they know it all.So, if a leader tries to lead through cleverness,He is nothing but a liability.But if a leader leads, not through cleverness, butthrough goodness, this is a blessing to all.To be always conscious of the Great PatternIs a spiritua virtue.Spiritua virtue is awesome and infiniteAnd it leads All things back to their Source.Then there emerges the Great Harmony.66Rivers and the sea are able to rule the streams of a hundred valleys.Because they are good at taking the lower position,The streams of a hundred valleys run to them.Therefore, if you want to rule effectively over peopleYou must surely speak as if below them.If you want to lead well,You must surely walk behind them.That way when the Sage takes a position of powerThe people will not fee oppressed.And when the Sage leadsThe people will not think he is in the way.Therefore the whole world joyfully praises himand does not tire of him.Because he refuses to compete,The world cannot compete with him.67Everyone says this Tao of mine is great and nebulous.So great, in fact, that it is too nebulousTo be of any use.I have three treasures that I hold and cherish:One is called compassionAnother is called moderationAnd the third is called daring not to compete.With compassion, one is able to be brave.With moderation, one has enough to be generous with others.Without competition, one is fit to lead.Nowadays people dont bother with compassion But just try to be brave.They scoff at moderationAnd find they have little enough for themselves.They step on people in their rush to be first-This is death!One who is compassionate in warfare is victoriousAnd in defense he holds fast.When Heaven moves to save someoneIt protects him through compassion.68The best soldier is not violent.The best fighter is not driven by anger.The true conqueror wins without confrontation.The best employer is humble before his employees.I say there is much good in not competing.I call it using the power of the people.This is known as being in tune with Heaven, Like the Sages of old.69The military has a saying:I would rather be passive, like a guestthan aggressive, like a host.I would rather retreat a footthan advance an inch.This is called going forward without instigating,Engaging without forceDefense without hatredVictory without weapons.There is no greater calamity than underestimating the enemy.If I take my enemy too lightly, I am in danger of losing mycompassion, moderation and non-competitive spirit.So, when two armies confront each otherVictory will go to them that grieve.70My words are very easy to understandAnd very easy to practice.Yet the World is not able to understandNor able to put them into practice.My words speak of the primal.My deeds are but service.Unless people understand thisThey wont understand me.And since so few understand me,Then such understanding is rare and valuable indeed.Therefore the Sage wears common clothesAnd hides his treasures only in his heart.71She who knows that she does not know is the best off.He who pretends to know but doesnt is ill.Only someone who realizes he is ill can become whole.The sage is not il because she recognizes this illness as illness,Therefore she is not ill.72When people lose their fear of powerThen great power has indeed arrived.Do not intrude on the peoples materia living.Do not despise their spiritua lives, either.If you respect them, you will be respected.Therefore the Sage knows himself,But he is not opinionated.He loves himself, but he is not arrogant.He lets go of conceit and opinion, and embraces self-knowledge andlove.73A soldier who has the courage to fight will eventually be killed.But one who has the courage not to fight will live.In these two, one is good and the other harmful.Who knows why Heaven allows some things to happen?Even the Sage is stumped sometimes.The Way of Heaven Does not compete, but is good at winning;Does not speak, yet always responds;Does not demand, but is usually obeyed;Seems chaotic, but unfolds a most excellent plan.Heavens net is cast wideAnd though its meshes are loose,Nothing is ever lost.74If people do not fear deathHow can you threaten them with it?If people live in constant fear of death,Because those who break the law are seized and killed,Who would dare to break the law?There has always been an officia executioner.If you take the law into your own handsAnd try to take his place, It is like trying to take the place of amaster carpenterIn which case you would probably hurt your hands.75The people are starving because their leaders eat upAll their money in taxes.And so, they are hungry.The people are rebelliousBecause their leaders are intrusive.And so, they protest.The people make light of death because their leaderslive so well at their expense.And so, they expect death.Therefore, it seems that one who does not grasp this lifetoo tightly is better off than one who clings.76When people are alive they are soft and weak.At their death they are hard and rigid.All young things, including grass and treesAre soft and frail.At their death they are withered and dry.So, All that are hard and rigid take the company of death.Those who are soft and weak take the company of life.Therefore, powerfu weapons will not succeed(Remember that strong and tal treesare the ones that are cut down).The strong and rigid are broken and laid low.The soft and weak will always overcome.77The Tao of Heaven is like the stringing of a bow.The high is pressed down and the low is raised up.The string that is too long is shortenedand the string that is too short is added to.Heavens Way is to take from what has too muchAnd give it to what does not have enough.This is not the way of men, however,For they take from those who have littleTo increase the wealth of the rich.So who is it that has too muchand offers it to a needy World?Only someone who knows the Tao.Therefore, the Sage works anonymously.She achieves great thingsBut does not wait around for praise.She does not want her talents to attract attention to her.78In the whole World nothing is softer or weaker than water.And yet even those who succeed when attacking the hard and the strongcannot overcome itBecause nothing can harm it.The weak overcomes the strong.The soft conquers the hard.No one in the World can deny thisYet no one seems to know how to put it into practice.Therefore the Sage saysOne who accepts a peoples shame is qualified to rule it.One who embraces a condemned people.is called the king of the Universe.True words seem paradoxical.79When enemies are reconciled, some resentment invariably remains.How can this be healed?Therefore the Sage makes good on his half of the dealAnd demands nothing of others.One who is truly good will keep his promise.One who is not good will take what he can.Heaven doesnt choose sid
