People are usually very nervous about fully experiencing the bright and colorful world. Nobody can see this level of relative truth without having cut through all the aspects of ego, because there is still a little attachment. People may see blue as blue, but at the same time, they use that to reinforce their idea of how blue affects their state of mind. Whether they regard things as powerful, good, nice, or threatening, there are always psychological implications behind the colors, forms, noises, and physical sensations they perceive. There is always some implication behind the whole thing. So the relative truth, is very difficult to experience fully, although it is very ordinary.
