The teaching of the disciples in Gurukul had been completed and today was his last day. According to Gurukul's tradition, Guruji was preparing to give the last sermon to his disciples. When all the disciples got into the main room of Gurukul, Guruji began to give up his preaching. They had some wooden toys in their hands. He said to the disciples, showing these toys, "These toys are in my hands. You have to find the difference between these three." By following Guruji's instructions, the disciples began to look at toys with great care. They were all three wooden toys, they were very similar looking goods. It was very difficult to find the difference.
Then a disciple inspected a guddy and said, "Hey, this is a hole in his ear." This sign was quite a lot, so all the disciples have discovered the difference in one and the other. So all of them spoke to Guruji that Guruji is the only difference in this gaddo that one has a hole in his ears. In one's mouth and one ear has a hole and one has only one ear hole.
Guruji, after listening to his answer, said absolutely right now Guruji gave the students a thin string of metal and put them in the ear of Gaddo. If the disciples did the same thing, then what is seen is that the wire gets out of the other ear while passing through the ears of a guddle. Through the ears of another guddle, that wire came out of the mouth. When one was putting the wire in one's ears, it did not come out of the form.
Guruji explained to him that in this way you will find three types of people in life. The one from whom you 
say something, then he listens with one ear and removes it from the other ear. Do not share anything with such people. There will be people who will listen to your words and say in front of someone else, do not share any ego thing with them, and one person will tell you whatever you can trust, like the same third house, You can also get advice about the matter. Such people will become your strength All you need to do is correct testing of the logo.
It is necessary in life to test right and confidant people
