대순환, or "Great Cycle," refers to the concept of cyclical time in various philosophical and spiritual traditions. It suggests that events and experiences in the universe repeat in a series of cycles, influencing the rise and fall of civilizations, natural phenomena, and human life. This idea is often associated with the belief in the interconnectedness of all things. In the context of Korean philosophy, 대순환 emphasizes the importance of understanding these cycles to achieve harmony and balance in life. It encourages individuals to reflect on their actions and their impact on the greater cycle, promoting a sense of responsibility towards oneself and the environment.
