4. Gentleness is sure to be victorious even in battle, and firmly to maintain its ground. Heaven will save its possessor, by his (very) gentleness protecting him.
68.
He who in (Tao's) wars has skill
Assumes no martial port;
He who fights with most good will
To rage makes no resort.
He who vanquishes yet still
Keeps from his foes apart;
He whose hests men most fulfil
Yet humbly plies his art.
Thus we say, 'He ne'er contends,
And therein is his might.'
Thus we say, 'Men's wills he bends,
That they with him unite.'
Thus we say, 'Like Heaven's his ends,
No sage of old more bright.'
69. 1. A master of the art of war has said, 'I do not dare to be the host (to commence the war); I prefer to be the guest (to act on the defensive). I do not dare to advance an inch; I prefer to retire a foot.' This is called marshalling the ranks where there are no ranks; baring the arms (to fight) where there are no arms to bare; grasping the weapon where there is no weapon to grasp; advancing against the enemy where there is no enemy.
2. There is no calamity greater than lightly engaging in war. To do that is near losing (the gentleness) which is so precious. Thus it is that when opposing weapons are (actually) crossed, he who deplores (the situation) conquers.
70. 1. My words are very easy to know, and very easy to practise; but there is no one in the world who is able to know and able to practise them.
2. There is an originating and all-comprehending (principle) in my words, and an authoritative law for the things (which I enforce). It is because they do not know these, that men do not know me.
3. They who know me are few, and I am on that account (the more) to be prized. It is thus that the sage wears (a poor garb of) hair cloth, while he carries his (signet of) jade in his bosom.
71. 1. To know and yet (think) we do not know is the highest (attainment); not to know (and yet think) we do know is a disease.
2. It is simply by being pained at (the thought of) having this disease that we are preserved from it. The sage has not the disease. He knows the pain that would be inseparable from it, and therefore he does not have it.
