Interesting science on how plants transmit light from surface into roots and out into otherwise-dark soil. Light triggers a cell, phytochrome, to produce a growth-guiding protein in plant leafs and shoots. This same type of cell exists in root tissue, and light received at the root tips via the plant’s light channeling fibers helps guide root growth via phytochrome.
Like plants, on the surface we receive sunlight and its archetypal analog, consciousness. Underground, at our roots, within us, we see that light reflected in elemental waters. The partner in polarity of the sunlight is the moonlight, as fire is to water, as consciousness is to subconsciousness.
“May peace be upon you.” Perhaps ‘you’ are the roots, and upon you the peace of a healthy plant. The plant too, or a human stewarding it, can be the ‘you’, and peace may be upon ’em too.
