8. The Knowledge of the Spiritual Essence of the World

By developing a world of images in us in this way, as I have described it, using very precise methods — you will find them described in the books mentioned — that are as exact as any mathematically exact investigation, by developing such images within us , we come to the point where we are no longer dependent on an external light, for example, but we experience a light inwardly, in that we experience ourselves, in that we feel ourselves placed with our soul and spirit outside our body in a spiritual world, we feel a light connected with our being. We live and weave in the light, and the light is not just something that makes things visible to us externally, as is the case in the sense world, but we ourselves become the light, the radiance of the light. In this way we make the spiritual entities visible to ourselves. At first we experience them in images; but the images are illuminated inwardly. Therefore, it should not be spoken of in a nebulous sense – I already hinted at this on Tuesday – but in an exact sense, from which one can speak in the same way as one speaks exactly about mathematics, of what the spiritual researcher acquires: exact clairvoyance, exact clairvoyance.
