Tao Te Ching 67.3

And Joshua said unto them, Fear not, nor be dismayed, be strong and of good courage: for thus shall the LORD do to all your enemies against whom ye fight.

Sugriva joyed as Rama spoke, And valour in his breast awoke. His eye grew bright, his heart grew bold, And thus his wondrous tale he told:

“Vaisampayana said,--“Arjuna who had obtained that excellent of bows and that couple of inexhaustible quivers, and that car with that banner, as also that assembly room, now addressed Yudhishthira and said,--‘I have obtained, O king, a bow and weapons and arrows and energy and allies and dominions and fame and strength. Those are always difficult of acquisition, however much they may be desired. Learned men of repute always praise in good society nobleness of descent. But nothing is equal to might. Indeed, O monarch, there is nothing I like more than prowess. Born in a race noted for its valour, one that is without valour is scarcely worthy of regard. One, however, possessed of valour, that is born in a race not noted for it, is much superior to the former. He, O king, is a Kshatriya in every thing who increaseth his fame and possessions by the subjugation of his enemies. And he that is possessed of valour, though destitute of all (other) merits, will vanquish his foes. One, however, that is destitute of valour, though possessed of every (other) merit, can scarcely accomplish anything. Every merit exists by the side of valour in an incipient state. Concentration of attention, exertion and destiny exist as the three causes of victory. One, however, that is possessed of valour doth not yet deserve success if he acts carelessly. It is for this that an enemy endued with strength sometimes suffers death at the hands of his foes. As meanness overtakes the weak, so folly sometimes overtakes the strong. A king, therefore, that is desirous of victory, should avoid both these causes of destruction. If, for the purpose of our sacrifice, we endeavour to slay Jarasandha and rescue the kings kept by him for a cruel purpose, there is no higher act which we could employ ourselves in. If, however, we do not undertake the task, the world will always think us incompetent. We have certainly the competence, O king! Why should you, therefore, regard us as incompetent?

Nay, verily. They fear not the Hereafter.
