2. Spiritual Science as Preparation for a New Etheric Vision

This Silver Age was followed by an age in which there still existed a clear knowledge, a kind of true knowledge of the spiritual world; yet by that time the human being had already descended sufficiently deeply into the physical, sensible world to be able to choose between the two worlds and to have his own convictions concerning them. The old clairvoyance became darker and darker during this third age, the Iron Age or Dvapara Yuga. Nevertheless, it still existed to a certain extent in a twilit state and the human being could, as a result of his own conviction, connect himself more or less with the spiritual world. He had formerly experienced this spiritual world, and this he still knew during the Iron Age.
