The Ynglist svadebnik (свадебник, "wedding") symbol, representing the two polarities of the energetic flow of the universe (the Ynglia, the enlivening and ordering radiance of the supreme God), the rightwise masculine fiery energy of the north pole (ха, ha 卍) and the leftwise feminine watery energy of the south pole (тха, tha 卐), which when forming the human body by passing through its nine energetic centres (chakras) converge into a point in the region of the heart where they become harmonised, and the thus reunified energy unfolds as a spinning cross.
