Symbiosis: a mutually beneficial relationship between different people or groups who hold opposing point of view or beliefs.
This is another excellent example of the symbiotic relationship between the Light and the dark.
Did you know, the Poinsettia’s folks love so much during the winter, only turn color by being exposed to the dark? Otherwise, they would remain commonly green. This gorgeous and symbolic plant, needs both the Light and the dark, to be uncommonly colorful. They literally have to be kept in total darkness for an extended period of time, in order to turn a magnificent red.
Google says: From October 1 to December 1, (or for at least 40 days) a poinsettia will need a strict light / dark regimen to produce color. Provide 13 to 16 hours of complete and uninterrupted darkness daily.
Anything TRULY beautiful, has been exposed to the dark, in order to become so.
Let that sink in, and water your roots Beacons!
