However, the natural symbol, without our being sufficiently conscious of the fact, is identical with the reality of the world that appears to us, for every object in the natural world is at the same time a symbolic reality to us. The psyche certainly does not use an "object" of nature as a "symbol," but rather the experience of an "object" itself is always already symbolic experience. The star or tree in us is no less real and no less symbolic than it is in outward experience. For each possibility of experience either presupposes a spiritually forming, that is to say a symbolic activity, or is identical with this. That is, everything spiritual appears to us first not just in nature but as nature; or we could formulate this just as well the other way around: everything natural, whether outward or inward, appears to us as an image, that is to say as formed spirit. We are surrounded by images, inwardly and outwardly, but at the same time formed and determined in all our experiences by the natural symbol as though by a unitary natural-spiritual reality, for our psychic system only grasps that which appears to us as the real world through the world of natural symbolism.
