The quote "The way is not in the sky. The way is in the heart," often attributed to Buddha, underscores that enlightenment and understanding are not found in distant, external places but within oneself. It emphasizes that true spiritual growth comes from introspection and personal insight, not from seeking answers outside. In Buddhist thought, the 'heart' symbolizes the center of consciousness and emotion, highlighting the importance of inner reflection and ethical behavior in one's spiritual journey.
