Excerpt from the original CRV Manual by Paul H. Smith:
Stage II presents to the viewer’s cognition signal line data relevant to physical sensory input. The classic explanation of this is that such data are exactly equivalent to “sensations the viewer would experience were he physically present at the site.” In effect, this allows the viewer to come into closer contact with the signal line through recognition and objectification of sensory facts relevant to the site. This information centers around the five physical senses: touch, smell, sight, sound, and taste, and can include both temperature (both as a tactile “hot/cold to the touch” sensation, and/or a general environmental ambience) and “energetics” (i.e., magnetism, strong radio broadcasts, nuclear radiation, etc.).
