"空 (Emptiness)" is a concept in various philosophical and spiritual traditions, particularly in Buddhism. It refers to the idea that all things lack inherent existence and are interdependent. This means that nothing exists in isolation; everything is connected and influenced by other factors. In Buddhist teachings, understanding emptiness helps individuals realize that attachment to fixed identities and material possessions can lead to suffering. By recognizing the transient nature of life and the interconnectedness of all beings, one can cultivate a sense of peace and compassion, ultimately leading to enlightenment.
