Panchatantra

"We ought to do our neighbor all the good we can. If you do good, good will be done to you; but if you do evil, the same will be measured back to you again."

"It has been the providence of Nature to give this creature [the cat] nine lives instead of one."

"There is no gathering of the rose without being pricked by the thorns."

"Wise men say that there are three sorts of persons who are wholly deprived of judgment,—they who are ambitious of preferment in the courts of princes; they who make use of poison to show their skill in curing it; and they who entrust women with their secrets."

"Men are used as they use others."

"What is bred in the bone will never come out of the flesh."

"Guilty consciences always make people cowards."

"Whoever … prefers the service of princes before his duty to his Creator, will be sure, early or late, to repent in vain."

"There are some who bear a grudge even to those that do them good."

"There was once, in a remote part of the East, a man who was altogether void of knowledge and experience, yet presumed to call himself a physician."

"He that plants thorns must never expect to gather roses."

"Honest men esteem and value nothing so much in this world as a real friend. Such a one is as it were another self, to whom we impart our most secret thoughts, who partakes of our joy, and comforts us in our affliction; add to this, that his company is an everlasting pleasure to us."

"That possession was the strongest tenure of the law."

"Hindu literature is especially rich in fables; indeed, India is probably responsible for most of the fables that have passed like an international currency across the frontiers of the world. Buddhism flourished best in the days when the Jataka legends of Buddha’s birth and youth were popular among the people. The best-known book in India is the Panchatantra, or “Five Headings” (ca. 500 A.D.); it is the source of many of the fables that have pleased Europe as well as Asia."

"The influence of the Panchatantra upon the Arabian Nights, however, is beyond question."

"[Arvind] Sharma recommends introducing the study of Arthashastra in all schools in all languages. ....Some others suggest that Panchatantra ought to be taught at very young ages as a popular version of strategic thinking. It is interesting that the Arabs took the Panchatantra and translated/adapted it into their children's stories, which reached Europe as Aesop's Fables."
