The Great Epic of the Bhārata dynasty 5.33.18

5.33.18

yasya kṛtyaṃ na jānanti mantraṃ vā mantritaṃ pare |
kṛtamevāsya jānanti sa vai paṇḍita ucyate || 18 ||

He whose intended acts, and proposed counsels remain concealed from foes, and whose acts become known only after they have been done, is considered wise. He whose proposed actions are never obstructed by heat or cold, fear of attachment, prosperity or adversity, is considered wise. He whose judgment dissociated from desire, followeth both virtue and profit, and who disregarding pleasure chooseth such ends as are serviceable in both worlds, is considered wise. They that exert to the best of their might, and act also to the best of their might, and disregard nothing as insignificant, are called wise. He that understandeth quickly, listeneth patiently, pursueth his objects with judgment and not from desire and spendeth not his breath on the affairs of others without being asked, is said to possess the foremost mark of wisdom. They that do not strive for objects that are unattainable, that do not grieve for what is lost and gone, that do not suffer their minds to be clouded amid calamities, are regarded to possess intellects endued with wisdom. He who striveth, having commenced anything, till it is completed, who never wasteth his time, and who hath his soul under control, is regarded wise. They that are wise, O bull of the Bharata race, always delight in honest deeds, do what tendeth to their happiness and prosperity, and never sneer at what is good.
