This paper mainly focuses on the issue of "turning the wheel of the dharma" (dharma-cakra-pravartana) and "a subsequent turning of the wheel of the dharma" (dharma-cakra-anupravartana) concerning the transmission and spread of the Buddha's teachings. Special attention is paid to the following four closely related subjects: pace-time, identity, belonging, and self. These four subjects, on the one hand, have long perplexed many philosophers, on the other hand, are what the Buddha's teachings can contribute to philosophy by examining the process of conceptualization therein. After defining these four subjects, this paper proceeds along three separate but related strands. The first is explaining how ordinary people are inclined to be trapped in the thought of pacetime, identity, belonging, and self. The second is emphasizing the authentic Dharma in the transmission and spread of the Buddha's Teachings. The third is demonstrating that a solid training in the authentic Dharma, a flexible strategy for converting sentient beings to Buddhism, and an unattached attitude in guiding sentient beings are all crucial factors for a really qualified preacher of the Buddha's teachings. By way of these three strands, the transmission and spread of the Buddha's teachings can actually help sentient beings liberate from the suffering in life and death.
