A guest who is full of spiritual light, truth speaker, well wisher of all, scholar and yogi when comes to our house, we should serve him with sweet and polite speech, food and different things of his interests. We should please him with these things. After that with conversation with him we should get knowledge of religion, getting money, completing our desires and getting salvation too. And we should make our character and actions according to his teachings. A ruler and other house masters are too the persons who may get full entertainment at our house.
A guest is called god [A god is that who gives something] because he after coming to our house gives us pleasure, different information or different things for our children etc. that is why he is called god.
Now we must understand well that every guest is not just like a god. The persons who criticize negatively the true knowledge, whose behavior is opposite the behavior decided by our constitution, liar, having actions like a cat who fills its stomach by snatching the rat etc at once from its place, are not the persons who may get entertainment. We should not entertain them even with our speech. We should not give them anything and should not speak them a single word of politeness. Because if we serve them and think that he is a guest-god, we may loss our progress after getting the bad inspirations from their life. This type of persons act negatively and inspire others to do so that is why they are not able to get any entertainment. These persons are called 'Pakhandi'. We can look at the following verse which is taken from 'ManuSmriti':
Pakhandino vikramsthan vaidal vrittikan shathan. Hetukan vakvritteenshch vangmatrenapi narchayet.
Actually, the persons who are not able to get any entertainment should not be rebuked. Because if we become angry on them, it will not be possible to improve their behavior in future. So we should use polite words to every one but some situations need punishment too. So it is said that -
"Samay ke anukul karm karna chahie." Lord Krishna made this proverb true. which means, we should act according to the need of time.
Now, when we see the other phase of this thought we find that serving and protecting anybody else will not go in vain. For it, I am narrating a story which is related to Lord Manu.
Similarly serving others makes a man strong. Actually 'serving is the power of woman', is said by some scholar. Any work what we do never goes waste. That is why we should do something positive and should not waste our time.
We should behave every one politely except some wicked persons.
I have studied Urdu literature too. Similar story is found in this literature with some little changes.In that literature that story is found with name 'Nooh ki Kashti'.
