Always respect food. Eat it without criticizing. Express pleasure on seeing food and pray for receiving it forever.
Like a jar of water, when overturned, empties all its contents, never to receive them back, thus should one give away without regard to money, fame, one's progeny, or even our own body to anybody who approaches us with a wish list.
Introduction to Jataka
Those who cook food (only) for themselves eat only sin.
Bhagavad Gita 3.13
Old age stands threatening like a tigress. Diseases are striking the body like enemies and life is leaking out like water from a broken jar; but, strange to say, men are still regardless of doing good.
There is no worse emaciation of the body than worry.
In this world nobody is ever seen doing anything without desire. Whatever a man does it is because of desire.
Desire is the biggest disease in the world; infatuation the biggest enemy; anger the greatest fire; and knowledge the highest pleasure in the world.
Chanakya Neeti Darpan: 5.12
Nights are demonic.
A walking man lifts his second leg only after the first has been placed firmly on the ground. A caterpillar leaves a blade of grass only when it has caught hold of another; similarly does the embodied soul, following the course of its destiny, leave the former body only when it has caught hold of the next.
Bhagavata Purana 10.1.40
For men too much walking, for horses being tied up, for women the lack of copulation, and for clothes exposure to sunshine - all lead to deterioration and old age.
Chanakya Neeti Darpan: 4.17
That which was before is only what takes birth again. What happens before happens now and that is what will happen in the future too. It is the father who enters his son with all his powers.
Atharva Veda 11.4.20
From birth, there are three instructors of a man: his guru, his father and his mother.
Valmiki Ramayana, 2.111.2
A person exceedingly angry is blind though possessed of eyes.
Weak persons acquire their objects when allied with the strong. The rivulet, with the help of the river, reaches the ocean.
Shishupalavadha BkII 100
Physical penance (tapas) means celibacy and non-violence. Mental penance is restraint of the mind and speech.
Mahabharata Shanti Parva 217.17
Father, mother, brothers and sons, all follow their own individual destinies. It is only the wife who shares her husband's destiny.
May the son follow his father and obey his mother. May the wife speak with her husband in a calml and sweet voice.
Atharva Veda 3.30.2
Even though beseeched by desire, never go near your wife during her menstrual period; nor lie with her on the same bed.
O you the Ketaka plant, you are curved, you grow in a muddy place, you are not easy of reach, snakes take recourse in you, you have no fruit, you have thorns, still you through your smell, are dear to all beings. Just one, single, good quality of yours cancels out all the bad ones.
The fish which lives deep in the sea gets caught, the deer which runs faster than the wind gets bound, even the bird, which can discern a piece of meat from a distance of several miles cannot see the net nearby - all because of the vagaries of fate.
Padma Purana. 2.81.28-29
