We speak of a mental continuum. We say of, compound phenomena dissociated from form and mind that they also depend on their directional parts. As for non-compound space itself, we speak of the south of space, the east, etc. In other words, when through analytical method we seek the phenomenon behind its appearance, it is unfindable. This is the most profound way to understand the principle of interdependence.
Phenomena exist, therefore, as denominations.
No phenomena exist otherwise. However, everything which can be designated by the mind does not necessarily exist. The most difficult thing is to determine, among all the things imputed by the mind, which ones exist and which do not. Even while we deny the autonomous and independent status of existents, we must not fall into the trap of an exaggerated relativism in which everything the mind conceives of is real. The problem now is to determine which criteria will enable us to find out which phenomena among ail those designated by the mind actually do exist.
