An article by Jessica Miller that talks about her visit to Mount Kurama.
“Mt. Kurama is the mountain near Kyoto, Japan, upon which Mikao Usui once meditated for 21 days and received the Reiki energy. I had visited Mt. Kurama in 2000, but in the fall of 2001, I decided to make a 21-day thank you pilgrimage to Mt. Kurama as part of a Reiki research trip. I even went a 22nd time.”
