Nubs are basically energetic representations of flowers that I invented to save myelf from having to study the enless landacape that is the flower. Generally, I don't engage in symbology or representative danglings, yet to me, Nubs are a cross between a the thought of a sunflower and chakra energy. Nubs give me a form with which to express joy, and I just happened to pick a floral form. Nubs basically are the flower of RAS, and I use them often.
