An important source of inspiration are Kabbalah teachings about the "lights", relating them to the Sephirot or emanations of the soul. Each of the modules is constructed with a special color scheme and visual dance which correlates to ideas about the specific Sephirot.
Light 7 YesodFoundation
An added input is a meditation suggested by the great Safad kabbalist of the 15th century, the Holy Ari (Luria), which is to visualize in the flames upon lighting the candles each night a marriage or "zivug" of the letter nun נ in the shamash, with the last eight letters of the Hebrew alphabet:
the first night נ-ס, the second night נ-ע and so on. All of the eight consecutive combinations make a two-letter word in Hebrew (itself a rare occurrence). Somehow these two letter "words" do mysteriously appear in the modules and not because of any premeditation on my part.
