here's another passage that caught my interest:

One researcher theorizes that spiritual phenomena could be explained in terms of electromagnetism. "All of us emit electromagnetic radiation over the whole range of wavelengths (called black-body radiation), though most of the energy comes out as infrared...Human microwave emissions can be measured by modern techniques termed microwave radiometry. This allows the minuscule amounts of energy we each emit, at wavelength of a centimeter or so, to be monitored" (Taylor 1980:29). By itself, however, electromagnetism doesn't appear to have enough force to cause spiritual phenomena. But a theory of some kind of field around the body may hold more promise. Sheldrake's (1981) theory of morphogenetic fields holds that chemical, physical and biological systems are guided and shaped by fields that exert their influence by means of morphic resonance. "As an example, one can say that the reason a plant cell becomes a leaf cell and not a root cell is because it tunes in, as it were, through morphic resonance, with the morphogenetic fields of all previous leaves of the same kind" (Dossey 1989:192).
