Mikao Usui's skills as a healer and teacher must have been very good and his fame spread very quickly throughout Japan. This was a time of great change in Japan, opening up to the West and changes both in government and religion. His teachings became popular among the older people who saw them as a return to old ideals and spiritual practices. His school/clinic was formed not just for the spiritual teachings but it was also a way for people to obtain healing. As people in general at this time in Japans history were very poor, healing sessions were very cheap or free. According to Japanese history articles, healing and other similar practices at that time would be given for a minimal cost or more likely for free. Reiki students seem to have worked with the teacher as a sort of payment (a small monetary fee might also have been involved).
