Tàijí is the moment before distinction. In Neo-Confucian cosmology it is the 'Supreme Ultimate' or 'Supreme Polarity' — not a god but a generative singularity from which yin and yang unfold. The famous opening of Zhou Dunyi's Taijitu shuo (c. 1073 CE) sets the sequence in motion: Wújí gives rise to Tàijí; Tàijí moves and generates yáng; at the limit of movement it becomes still and generates yīn.
This is not static monism. Tàijí is the axis of a cosmic breathing — the one that contains the two, the undivided source of all subsequent differentiation.
