The mind of Tao is in this text associated with ‘celestial’ yang, in contrast to the ‘human mind,’ or human mentality, associated with ‘mundane’ yin. The human mentality is regarded as lacking stability and being subject to acquired conditioning
This passage establishes the canonical definition of the Mind of Tao as the yang-celestial pole of psychic life, structurally opposed to the conditioned, unstable human mentality.
