Self-awarenessis a key concept in Song-Ming Neo-Confucianism,primarily referring to the self-initiated,introspective activity of the mind.This inward activity parallels reflection in modern philosophy.Self-awareness involves aligning with the principle of heavenly order and achieving unity of mind,thereby clarifying one's true nature.Neo-Confucian scholars believed that natural impurities obscure innate nature,and that self-awareness is the mind's response to these impurities,purifying disposition to illuminate one's nature.This unity of mind also brings clarity to one's true nature;awareness of one's nature is also an awakening to one's identity,forming subjectivity.Recognizing one's nature means accepting and following principle;self-awareness of heavenly order is thus a transcendent activity in alignment with"Li"(理).
