At one point of his life, he became a monk and lived in a monastery near mount Kurama in Kyoto. He was looking for way to heal himself and others without depleting his own energy, in which he could feel that this way of healing exists. He decided to take 21 days meditation on the top of mount Kurama, which also included praying and fasting. On the 21st date, powerful light entered his mind through top of his head and caused him to fall unconscious. This was the time he received reiki attunement, and the first time the reiki energy has come on earth. He came down from mount Kurama and set up reiki clinic in Kyoto to start giving healing to others. Before his death in 9 March 1926, he trained around 16 reiki masters to make sure that reiki will stay and spread all over the world.
