Kuji is a traditional Japanese practice that involves the use of hand gestures, or mudras, to channel spiritual energy. It is often associated with Shingon Buddhism and Ninjutsu, where practitioners believe these gestures can invoke protective powers and enhance meditation. The term "Kuji" translates to "nine characters," referring to the nine symbolic hand signs used in the practice. Each gesture corresponds to specific intentions, such as protection, healing, or wisdom. Kuji is often practiced alongside chanting mantras to deepen the spiritual experience and focus the mind.
