불교 만자와 북두칠성
Like other symbols such as the swastika,[26] wàn 卍 ("all things") in Chinese, the Mesopotamian 𒀭 Dingir/An ("Heaven"),[27] and also the Chinese 巫 wū ("shaman"; in Shangscript represented by the cross potent☩),[28] Tiān refers to the northern celestial pole (北極 Běijí), the pivot and the vault of the sky with its spinning constellations.[29] Here is an approximate representation of the Tiānmén 天門 ("Gate of Heaven")[30]or Tiānshū 天樞 ("Pivot of Heaven")[31]as the precessional north celestial pole, with α Ursae Minoris as the pole star, with the spinning Chariotconstellations in the four phases of time. According to Reza Assasi's theories, the wan may not only be centred in the current precessional pole at α Ursae Minoris, but also very near to the north ecliptic pole if Draco (Tiānlóng 天龙) is conceived as one of its two beams.[32][note 1]
