Ma Dexin (1794–1874), the prestigious Sino-Muslim philosopher, bridged Sufi ideas and Neo-Confucian philosophy by his handling of the concept of the Great Mandate. For Ma, the Sufi idea of ‘the Muhammadan Reality’, namely the reality of the perfect human, could be understood through an adoption and exploration of an ontological and cosmological interpretation of the Confucian concepts ‘sage’ and ‘ming’. The paper explains how Ma departed from the Neo-Confucian conceptual framework by holding that the Non-Ultimate had more ontological significance than the Supreme Ultimate. It is proposed that Ma's difference from the Neo-Confucians on that point explains his identification of the Great Mandate with the Non-Ultimate.
