The belief in heaven's mandate (tianming 天命) in earlier documents referred to divine-ethical sanctions of political rulers. It later developed multiple implications such as an individual's destiny or fate and became one of the most fundamental concepts in Chinese intellectual and cultural history. In modern times, this concept has received long-lasting attention in the field of Chinese philosophy, and almost all major scholars have more or less been involved in discussions and debates, especially on the topic of the classical Confucian conception of heaven's mandate. Their discussions on this topic have largely focused on two major controversies: (i) whether early Confucians view heaven's mandate as prescriptive ethical command or descriptive amoral fate, and (ii) whether their attitude toward heaven's mandate is voluntarist or fatalistic. While this scholarship has been fruitful and insightful, it has continued for almost a century with certain variants. Therefore, it is time to address this topic with new approaches and hermeneutic horizons. In this essay, I propose a new approach and horizon to viewing the classical Confucian conception of heaven's mandate as their reflections on individual existence and self-realization under the constraints of mandate or destiny. I examine the texts associated with Confucius and Mencius such as the Analects and the Mencius, as well as some recently unearthed texts, to suggest that early Confucians accommodate individual initiative and self-determination of life choices through their conceptualization of heaven's mandate. To them, the vocabulary of heaven's mandate empowers individuals, especially through situating their places in society and the cosmos. By knowing and standing firmly on one's mandate or destiny, the individual not only realizes the value of their existence but also goes beyond the ultimate destiny of death. This fresh reading of heaven's mandate is grounded in the context of the development of Confucian ideas in the early period and presents an optimistic vision of Confucian humanism.
