Truth, beauty, acquaintance with the scriptures, knowledge, high birth, good behaviour, strength, wealth, bravery, and capacity for varied talk,—these ten are of heavenly origin. A sinful person, by committing sin, is overtaken by evil consequences. A virtuous man, by practising virtue, reapeth great happiness. Therefore, a man, rigidly resolved, should abstain from sin. Sin, repeatedly perpetrated, destroyeth intelligence; and the man who hath lost intelligence, repeatedly committeth sin.
In plain words: Vidura lists ten gifts from heaven, such as truth, beauty, learning, good conduct, strength, wealth, and courage. Sinners meet bad results and good people find happiness, so a person should firmly avoid wrongdoing. Doing wrong again and again ruins your judgment, and with poor judgment you keep doing wrong.
