To discover the true significance of thinking, to find the real truth — that thinking has cosmic significance — it is necessary to progress to imaginative perception, as described in Knowledge of the Higher Worlds. Stripping our thinking of the abstract nature we consciously associate with it, and entering into that ocean of weaving thoughts, we encounter the necessity to have not only the abstract thoughts in there that we have as citizens of the earth but to conceive images in it. For everything is created from images.
Images are the true or origins of things; images are behind everything around us; and it is into these images we enter when we immerse ourselves in the ocean of weaving thoughts. Those are the images Plato spoke of; they are the images all who have spoken of spiritual primary causes had in mind, the images Goethe had in mind with his archetypal plant. These images are to be found in imaginative thinking. This imaginative thinking is a reality and we become immersed in it when we enter the billowing world of thoughts that move with the stream of time.
