The problem is that the average person's experience is limited to a relatively small range of scale, or size, and duration, or time. We perceive the nature of things only for objects near our own scale, and we don't experience events on the sub-microscopic, the planetary, or the cosmic level, for the most part. Consequently, those things which lie outside that range we can experience through the senses tend to be filed away as curiosities, rather than our breathing life into the concepts. However, there are ways in which events on a different level of scale can enter our awareness, and influence our daily life. Little things like electrons add up, and their movement within our body is key to the processes which support life.
Electrons are carriers of energy, in the form of electric charge.
There are numerous channels of energy flow in the body, and a multitude of processes involving electrons. Both Chiropractors and Practitioners of Chinese Medicine base their practice upon the assumption that proper energy flow is essential to health, and that energy blockages promote disease and should be eliminated. Certain oriental practices such as Tai Ji, Chi Gung, Kung Fu, and Aikido are said to derive their strength from the conscious movement of energy to create motion. What we can experience does depend upon our practices, as well as our beliefs, and upon the repertoire of techniques, or the ability of the teachers available to us. The only way we can really measure what we know is by applying known principles, and seeing how that works.
