1. Do not be very upright in your dealings for you would see by going to the forest that straight trees are cut down while crooked ones are left standing.
2. He who gives up shyness in monetary dealings, in acquiring knowledge, in eating and in business, becomes happy.
3. The wise man should restrain his senses like the crane and accomplish his purpose with due knowledge of his place, time and ability.
4. These five are your fathers; he who gave you birth, girdled you with sacred thread, teaches you, provides you with food, and protects you from fearful situations
5. The following qualities of the denizens of hell may characterise men on earth; extreme wrath, harsh speech, enmity with one’s relations, the company with the base, and service to men of low extraction.
6. No messenger can travel about in the sky and no tidings come from there. The voice of its inhabitants is never heard, nor can any contact be established with them. Therefore the brahmana who predicts the eclipse of the sun and moon, which occur in the sky, must be considered as avidwan (man of great learning).
7. The student, the servant, the traveller, the hungry person, the frightened man, the treasury guard, and the steward: these seven ought to be awakened if they fall asleep.
8. The student (brahmacari) should completely renounce the following eight things — his lust, anger, greed, desire for sweets, sense of decorating the body, excessive curiosity, excessive sleep, and excessive endeavour for bodily maintenance.
9. He alone is a true brahmana (dvija or “twice-born”) who is satisfied with one meal a day, who has the six samskaras (or acts of purification such as garbhadhana, etc.) performed for him, and who cohabits with his wife only once in a month on an auspicious day after her menses.
10. Those men who are happy in this world, who are generous towards their relatives, kind to strangers, indifferent to the wicked, loving to the good, shrewd in their dealings with the base, frank with the learned, courageous with enemies, humble with elders and stern with the wife.
11. What fault of spring that the bamboo shoot has no leaves? What fault of the sun if the owl cannot see during the daytime? Is it the fault of the clouds if no raindrops fall into the mouth of the chatak bird? Who can erase what Lord Brahma has inscribed upon our foreheads at the time of birth?
12. Courtesy should be learned from princes, the art of conversation from pandits, lying should be learned from gamblers and deceitful ways —–censored—-.
13. He who is not shy in the acquisition of wealth, grain and knowledge, and in taking his meals, will be happy
14. He who is overly attached to his family members experiences fear and sorrow, for the root of all grief is attachment. Thus one should discard attachment to be happy.
15. Excessive attachment to sense pleasures leads to bondage, and detachment from sense pleasures leads to liberation; therefore it is the mind alone that is responsible for bondage or liberation
16. There are three gems upon this earth; food, water, and pleasing words — fools (mudhas) consider pieces of rocks as gems.
17. We should always speak what would please the man of whom we expect a favour, like the hunter who sings sweetly when he desires to shoot a deer.
18. It is ruinous to be familiar with the king, fire, the religious preceptor, and a woman. To be altogether indifferent to them is to be deprived of the opportunity to benefit ourselves, hence our association with them must be from a safe distance.
19. If you wish to gain control of the world by the performance of a single deed, then keep the following fifteen, which are prone to wander here and there, from getting the upper hand of you: the five sense objects (objects of sight, sound, smell, taste, and touch); the five sense organs (ears, eyes, nose, tongue and skin) and organs of activity (hands, legs, mouth, genitals and anus).
20. A wise man should not divulge the formula of a medicine which he has well prepared; an act of charity which he has performed; domestic conflicts; private affairs with his wife; poorly prepared food he may have been offered; or slang he may have heard.
21. Sastric (scriptural) knowledge is unlimited, and the arts to be learned are many; the time we have is short, and our opportunities to learn are beset with obstacles. Therefore select for learning that which is most important, just as the swan drinks only the milk in water.
22. The heart of a woman.….….….….. —— censored ———-
23. The fool (mudha) who fancies that a charming young lady loves him, becomes her slave and he dances like a shakuntal bird tied to a string.
24. A king, a prostitute, Lord Yamaraja, fire, a thief, a young boy, and a beggar cannot understand the suffering of others. The eighth of this category is the tax collector.
