The Essence of Anthroposophy
Through this cognitive faculty, which he can still increase by, when he has, as it were, grasped this ability to love within, when he has become aware of it, by now pursuing the external facts in such a way that he really lovingly puts himself in the individual kingdoms of nature — I have described this in detail — as a person develops such cognitive abilities, as he lovingly follows the life of a plant from germination to fruit, so that he experiences how leaf by leaf unfolds. Likewise, one can — I would say — with such a developed capacity for love, delve into the animal organization and so on. If one also strengthens the life of the will in this way and begins to observe oneself more seriously than usual as an active human being, if one observes oneself in one's actions as objectively as one otherwise only observes external objects, if one gets into the habit of walking beside oneself like a second person and always watching oneself in his volitions, then the will comes to not only let inspiration unfold in man, but to let that which speaks into the human soul from a spiritual world also be experienced through the imagination. Then man comes to make his own soul a living organ of knowledge for the spiritual. In inspiration, the spiritual world does not yet reveal itself to the soul in a clear way. In the third stage, which I have called intuition — real intuition, not the vague one that one also speaks of in one's outer consciousness — in this intuition, man truly penetrates into the spiritual world.
