What is the best way of attaining spiritual knowledge? First one must develop in one's nature that little spark which is divine and which was shining in one's infancy, showing something pure, something of heaven. What attracts us most is innocence. It is innocence which gives an impression of purity, but we must not understand this wrongly. Knowledge of the world is more than necessary; it is needed to live in the world, to make the best of our life, to serve God and humanity - it is not needed to attain spiritual knowledge: innocence is necessary for that.
