Okuden is a Japanese word meaning 'inner teachings'. As the word implies a deeper understanding and connection to Usui Mikao’s teachings is achieved during this course.

This level teaches how to connect to Earth and Heaven energy, the first steps to becoming fully integrated with the universe. This is achieved through the practise of shirushi (symbols) and jumon (mantras). It will enable the student to enhance his/her own energy levels and sensitivity. There are many aspects to the shirushi and jumon which include chanting and visualisation techniques. Rather than being external tools - the focus here is on internal use for spiritual development.
