Then said a teacher , speak to us of teaching . And he said :The teacher who walks in the shadow of the temple among his followers gives not of his wisdom but rather of his faith and his lovingness.The astronomer may spaeak to you of his understanding of space , but he cannot give you his understanding.The musician may sing to you of the rythem which is in all space , but he cannot give you the ear which arrests the rythem nor the voice that echoes it .And he who is versed in the science of numbers can tell of the regions of weight and measure , but he cannot conduct you thither .For the vision of one man lends not its wings to another man .
Kahlil Gibran, The Prophet
