A mentor is a person whose guidance and retrospection can become your foresight. There are many people who think that they can mentor themselves such people always live in illusion. We are not born with knowledge so we should look for someone who can mentor us.
We have to be very careful while choosing the mentor. A good mentor will guide and give direction where as a bad mentor will misguide.
If you want to learn you have to show respect, be an interested student. An interested student gets the best out of teacher. The best teacher will not give you some think to drink, they will make you thirsty. They will put you on a path to seek answer
If god and teacher are standing together who does the student salute first? According to Indian culture, the answer is teacher, because without his direction and help the student could not have met god.
