The design refers to the abstract and stylized shape of a lotus flower as this is associated in many cultures as a symbol of spiritual evolution.
"The plant's growth can be seen as an allegorical elevation: The seed sprouts at the bottom of a pond and then pushes up through the layers of rocks and mud and water to the surface, where it finally blooms into a beautiful lotus blossom. This is a metaphor for mankind's struggle and evolution from a low and rocky bottom into spiritual awakening."
