The second condition necessary in the teacher is — sinlessness. The question is often asked, "Why should we look into the character and personality of a teacher? We have only to judge of what he says, and take that up." This is not right. If a man wants to teach me something of dynamics, or chemistry, or any other physical science, he may be anything he likes, because what the physical sciences require is merely an intellectual equipment; but in the spiritual sciences it is impossible from first to last that there can be any spiritual light in the soul that is impure. What religion can an impure man teach? The sine qua non of acquiring spiritual truth for one's self or for imparting it to others is the purity of heart and soul. A vision of God or a glimpse of the beyond never comes until the soul is pure. Hence with the teacher of religion we must see first what he is, and then what he says. He must be perfectly pure, and then alone comes the value of his words, because he is only then the true "transmitter". What can he transmit if he has not spiritual power in himself? There must be the worthy vibration of spirituality in the mind of the teacher, so that it may be sympathetically conveyed to the mind of the taught.
