Naikan is a form of introspection that originated in Japan. The practice involves reflecting on one's interactions and experiences with others, with the aim of gaining a deeper understanding of oneself and one's relationships. It is a method for self-reflection, self-improvement and personal growth. During a Naikan practice, a person reflects on their past interactions and experiences with others, focusing on three main areas: What they received from others What they gave to others What troubles and difficulties they caused others. The practice typically involves asking oneself questions such as: Who did I interact with yesterday? What did I receive from each person? What did I give to each person? What difficulties or conflicts did I experience? How have these interactions affected me? Naikan is often used as a therapeutic tool for addressing issues such as depression, anxiety, and relationship problems, as well as for personal growth and self-improvement. It is also used as a spiritual practice in some religious traditions.
