The disciple has to have full confidence in the teacher's guidance, in the direction that is given to him by the teacher. The Buddhists who regard a spiritual teacher with great reverence say, "We do not care whether he is well-known or not; and even if he is we do not know if he will accept our reverence; and if he receives it we are not sure he needs it." Worship can only be given to those of whose presence we are conscious; and it is especially intended for the spiritual teacher, for he shows us the only path that frees us from all the pains of which this life is full. That is why among all other obligations involving earthly gain and benefit the obligation to the spiritual teacher is the greatest, for it is concerned with the liberation of the soul on its journey towards Nirvana, which is the only desire of every soul.
