Infrared altitude signifies a degree of development that is in many ways imbedded in nature, body, and the gross realm in general. Infrared altitude exhibits an archaic worldview, physiological needs (food, water, shelter, etc.), a self-sense that is minimally differentiated from its environment, and is in nearly all ways oriented towards physical survival. Although present in infants, infrared is rarely seen in adults except in cases of famine, natural disasters, or other catastrophic events. Infrared is also used as a kind of catch-all term for all earlier evolutionary stages and drives.
