Plant nervous systems are as highly sensitive to electromagnetic fields as ours. This is necessarily so, since they use the electromagnetic energy of the sun in photosynthesis. They emerged as an ecological expression of Earth specifically to work with the electromagnetic spectrum. But the range of their sensitivity goes far beyond the spectrum of visible light. They can, in fact, detect and respond to broadband electromagnetic signals, as can all organisms.
And we, like plants, are evolutionarily designed to encounter such fields, just as the generators of those fields are designed to encounter us. The meanings embedded within those fields, experienced by us as emotions, affect the heart’s rate, hormonal cascade, pressure waves, and neurochemical activity. Directed emotions- intentional, informational electromagnetic embeds sent outward-affect those external electromagnetic fields in turn. Through such directed communication and perception, a living dialogue occurs between us and the world.
Such interchanges are a part of what it means to be human and have been a part of our interaction with our environment since we emerged out of the living field of this planet. But without a flexible heart, they cannot be perceived.
