A friend should be respectful, pure hearted, gentle and mighty. His behavior should be full of decency and his faith should be unshakable in truth. The search for such a virtuous friend is necessary because trusting in them can be depended on and any kind of deception can be avoided. Like making friends, one should also be careful in making relations with people of acquaintance. Only those people who are known are able to maintain contact. Which can bring us any kind of benefit. Knowing people can also be helpful in making our life enjoyable and best. Their position differs from that of a friend in this regard. They cannot help as much as a friend, man's life is too short. It does not have enough time to destroy it. Every moment of life's time should be used, our acquaintances should talk with us wisely and humorously. We should say good things. We should provide patience in crisis. We should be aware of duty. Join us in our happiness. If they cant do any of these for us, they have no place in our lives. It is fine to stay away from them. The association of bad people is as terrible as the disease of fever. Living with such people is a big loss. Due to fever, the human body becomes weak. In the same way, policy and good conduct are harmed by the company of bad people. Wisdom is destroyed. The power of man to understand the difference between good and bad deeds is destroyed. The association of bad people is like a stone mill tied on the feet. Due to this, he is not able to move forward on the path of progress, he gets down. The company of well mannered people is like someones arm. By taking their support, man continuously progresses.
