If a student is going down the correct path, no one will stop him. If he strays, a teacher will punish him with love. In that respect every one is free as long as they are going down the right path (of Dharma). What more freedom does one want? We are happy in this type of freedom which is in our teacher's hands.

If the students make good use of the education they got from the teacher, the teacher has to be given credit for it. It only shows his greatness. If a drop of pure water from the clouds falls as rain into the sea, it is up to the sea to see that it reaches an oyster and becomes a pearl. Only because the sea is able to do this, he is also called a gem-maker.
