The Talmud states that when a student is exiled, his teacher must be exiled with him. Not simply that he must go with him. He must be exiled with him.
Which tells us: If you truly want to teach, you must put yourself in your student’s space.
If your student has wandered far astray, tear yourself away from your own space; feel what it is like to be distant. If your student is in pain, let that pain become your pain. There must be nothing that lies between your student’s world and your own.
Teach in this way and you can bring even the most distant student to your own level of understanding. And yet higher: You will learn from this student that which you could never have learned from your own teachers and colleagues.
