This is one of the greatest challenges we have in everyday life: relationships. You have to have relationships with people at home, you have to have relationships with people at the place of work. We cannot move away from relationships. So let us take the case of someone in everyday life making your life miserable, creating problems for you, creating suffering for you. An interesting way of relating to such a person is to relate to that person as your teacher, as your guru. So you learn to use that person to observe your own mind, to see your own reactions to that person. Then you realise that the problem is not with that other person but how you are relating to him, how you are reacting to that person.
