Satori is a Japanese word that refers to a sudden moment of enlightenment or a profound spiritual awakening. It is often associated with moments of deep insight or understanding that fundamentally shift one's perspective on life. In Zen Buddhism, satori is considered a moment of clarity that can lead to a deep sense of liberation and freedom from suffering. Achieving satori is often seen as the ultimate goal of spiritual practice, as it is believed to bring a direct experience of truth and reality. In modern usage, the term satori is often used more broadly to describe moments of insight or significant personal growth.
