2. The Human Soul, Destiny and Death from the Point of View of Spiritual Science
The preparation for his research lies in what the spiritual researcher experiences here, when he excludes external reality and directs his gaze purely to inner thoughts and imaginative experiences, when he turns his attention entirely to his inner being. What happens in his inner being is what it is all about. What is going on in his mind, the extent of his inner experiences, can all be characterized by saying: The path of the spiritual researcher is through the concentration of thought.

Not that it is something different, it is basically only an intensification of what we otherwise also call attention in our external life; but it is an unlimited intensification of this attention.
