Depending and enjoying certain society, one has of course duties in ones relations of which are of many kind for a householder. One not coming after his duties increases debt and endangers to be cut off while still full of desires.
In regard of getting understood the means, ways and kind of approaches, judgement from a wise perspective, this generous work makes many things clear: Wisdom over Justice.
Particularly, if one part-takes in the Buddhas society, nourishes on it, even benefits from it, one would have those duties there:
"Now I will tell you the layman's duty. Following it a lay-disciple would be virtuous; for it is not possible for one occupied with the household life to realize the complete bhikkhu practice (dhamma).
"He should not kill a living being, nor cause it to be killed, nor should he incite another to kill. Do not injure any being, either strong or weak, in the world.
"A disciple should avoid taking anything from anywhere knowing it (to belong to another). He should not steal nor incite another to steal. He should completely avoid theft.
"A wise man should avoid unchastity as (he would avoid falling into) a pit of glowing charcoal. If unable to lead a celibate life, he should not go to another's wife.
"Having entered a royal court or a company of people he should not speak lies. He should not speak lies (himself) nor incite others to do so. He should completely avoid falsehood.
"A layman who has chosen to practice this Dhamma should not indulge in the drinking of intoxicants. He should not drink them nor encourage others to do so; realizing that it leads to madness. Through intoxication foolish people perform evil deeds and cause other heedless people to do likewise. He should avoid intoxication, this occasion for demerit, which stupefies the mind, and is the pleasure of foolish people.
Do not kill a living being;
do not take what is not given;
do not speak a lie;
do not drink intoxicants;
abstain from sexual intercourse;
do not eat food at night, at the wrong time;
do not wear flower-garlands nor use perfumes;
use the ground as a bed or sleep on a mat.
"This is called the eight-factored observance made known by the Awakened One who has reached the end of suffering.
"With a gladdened mind observe the observance day (uposatha), complete with its eight factors, on the fourteenth, fifteenth and eighth days of the (lunar) fortnight and also the special holiday of the half month. In the morning, with a pure heart and a joyful mind, a wise man, after observing the uposatha, should distribute suitable food and drink to the community of bhikkhus. He should support his mother and father as his duty and engage in lawful trading. A layman who carries this out diligently goes to the devas called "Self-radiant."
