Wu (Chinese: 悟) is a concept of awareness, consciousness, or spiritual enlightenment in the Chinese folk religion. According to scholarly studies, many practitioners recently "reverted" to the Chinese traditional religion speak of a "new awareness" (kai wu 开悟 or jue wu 觉悟) of the interconnectedness of reality in terms of the cosmic-moral harmony—ming yun, bao ying, yuan fen. This spiritual awareness works as an engine that moves these themes from being mere ideas to be motivating forces in one's life: awareness of ming yun ignites responsibility towards life; awareness of yuan fen stirs to respond to events rather than resigning. Awareness is a dynamic factor and appears in two guises: a realisation that arrives as a gift, often unbidden; then it evolves into a practice that the person intentionally follows.
In Latin alphabetical transliteration of the Chinese, it's a homograph of the wu-shaman.
