All the diversity in creation is created by the interaction of two forces – giving and receiving. Their interaction results in the formation of images which we clearly perceive, because these two forces unite inside a person. We don’t perceive the force of reception or the force of bestowal separately. We always feel their interaction, which depicts various images of the world inside us.
These images depend on the thickness of one’s desire (0, 1, 2, 3 and 4), which is the vessel in which the force of bestowal illustrates these qualities for a person. Depending on this, one feels the inanimate, vegetative, and animate objects in nature, or the human being (the soul) and the Upper World.
