The History of Usui Reiki

One day, Usui-Sensei climbed Mt. Kurama, where he began to do penance while fasting. Suddenly on the twenty first day from the start, he felt a great REIKI over his head, and at the same time as he was spiritually awakened he acquired the REIKI cure. When he tried it on his own body and members of his family also, it brought an immediate result on them. 
Having said “It is much better to give this power widely to a lot of people in the world and enjoy it among them than to keep it exclusively by his family members,” Usui-Sensei moved his dwelling to Aoyama Harajuku, Tokyo in April, 1922 and established an institute, where the REIKI cure was instructed openly to the public and the treatment was given, too. People came there from far and near to ask for his guidance and cure, and they over-flowed outside, making a long line. 
Tokyo had a very big fire caused by a great earthquake in Kanto district in September, 1923, when the injured and sick persons suffered from pains everywhere. Usui-Sensei felt a deep anxiety about that, and he was engaged in a cure, going around inside the city every day. We can hardly calculate how many persons were saved from death with his devotion. His activities of relief, in which he extended his hands of love over to those suffering people against this emergent situation, can be outlined as noted above.
