With this he resolved to find the way in which Jesus had healed. This immediately set him on a journey of many years. Studying first at Christian schools in the US, for where else to learn of Jesus, but with no results.  In the Christian schools the method was not known.

It was suggested he study Buddhist writings since the Buddha had also healed. This took more years studying at a monastery in the Orient. Nowhere could he find the answers. In Japan he toured many temples asking for knowledge of how the Buddha had healed.  At each one the priests said they were more concerned with spiritual than physical well being.  In one small monastery he found some ancient Sanskrit writings from India (or perhaps Tibet).  [Diane Stein's research suggests he found the sutras to invoke the Medicine Buddha, the invoking of this Buddha is a common practice in Tibetan Buddhism]  After a few more years of study, he felt he had come to an understanding and that to go further required in depth meditation.  He declared to the monks of this monastery his intention to fast and meditate for 21 days at a nearby mountain and that if he did not come back they should come and get his body.

He went to the mountain and gathered 21 stones with which to count the days.  Each day he would throw away a stone and in this way count the time.  On the 20th day nothing had come as yet and he threw away the last stone saying "Well, this is it, either I get the answer tonight or I do not".  In the night on the horizon he could see a ball of light coming towards him. The first instinct was to get out of the way, but he realized this might just be what he was waiting for, so allowed it to hit him right in the forehead. As it struck him he was taken on a journey and shown bubbles of all the colors of the rainbow in which were the symbols of Reiki, the very same symbols in the Tibetan writings he was studying but had been unable to understand. Now as he looked at them again, there was total understanding.

After returning from this experience he began back down the mountain and was, from this moment on, able to heal. This first day alone he healed a broken toe-nail, his own starvation, an ailing tooth and the Abbots sickness which was keeping him bedridden.  These are known as the first four miracles.

He wanted to use these abilities to help others, he spent the next seven years in the beggars section of Tokyo healing the poor and sick people there, sending them to a priest to assist finding them employment, and elevating them out of poverty. After the seven years he noticed familiar faces, those of people whom he'd healed long ago who were back again. Asking them, they complained that life outside beggartown was too hard and that it was much simpler to beg for a living.  They had thrown away the gift of health, as if it had no value, to return to the supposed comfort of the life they knew.

This threw Usui into a quandry and he returned to the monastery. From this he realized he hadn't taught gratitude along with the healing.  That he'd focused on the physical ailments without dealing with the spiritual matters. The people did not understand the value of the gift he gave them.

Dr. Usui returned to the monastery for further reflection and planning.  After some time in the monastery he developed precepts.  In this new plan he traveled around the countryside from village to village.  In each one he stood in a public place during the day holding aloft a lit torch.  When people told him he didn't need a torch in daylight, he answered was he was looking for the few who are interested in improving themselves.  In this way he traveled around teaching and healing, working both with the spiritual healing as well as physical healing.

Dr. Hayashi opened a clinic in Tokyo near the Imperial Palace.  It consisted of eight beds in a large room, two practitioners per patient.  One would treat the head and the other would be on the right treating the stomach area, then both would treat the patients back.  The practitioners all worked here doing healings.  They would also go to the homes of sick people for house calls.

To become a Reiki Practitioner in that time one had to be accepted by the masters in the Reiki organization, and second had to promise to use Reiki daily and volunteer some hours to practice Reiki regularly in the clinic.

Dr. Hayashi passed on Tuesday, May 10, 1940.  This was just prior to World War II and it was clear that Japan would enter the war.  Being a Reserve Officer, Dr. Hayashi knew he would be recalled to duty and therefore become responsible for killing many people.  This he did not want to do, and so determined to end his life.  In addition he wished to, and did, pass leadership over to Reiki to Mrs. Takata (perhaps because she would not be in Japan and therefore relatively safe and able to continue the practice).

After Mrs. Takata became well she wanted to learn this for herself.  However Dr. Hayashi was not willing to teach her because she was a foreigner.  Through the good graces of her doctor, Mrs. Takata was able to persuade Dr. Hayashi to train her in Reiki.  This training took a year and brought her to what we would now call Reiki Level II (she could do everything but train other practitioners).

After this year she returned to Hawaii.  In Hawaii she also learned the lesson of having the recipient perceive value in receiving treatments.  She treated a neighbor but did not charge, this neighbor did not value the treatments and did not become well.  She treated another relative and this time charged, and this relative did stay well.  Thus the tradition of charging for Reiki treatment was reinforced.

In November 1936 Dr. Hayashi came to Hawaii for a speaking tour to promote Reiki.  During this time he trained Mrs. Takata to teach Reiki, thus making her what we now would call a Reiki Master.  As he left Hawaii he asked her to come to see him when he summoned her.

After some more time it was nearing when World War II would start, the part in Europe already having begun.  Dr. Hayashi appeared to Mrs. Takata in a dream asking her to come to Japan.  She did this and found Dr. Hayashi having his Naval Uniform out of storage and fretful.  With the coming war he knew it was a matter of time before the Navy would call him out of retirement and he would be asked to perform actions he was not capable of doing due to his spiritual development.  At this time he passed to Mrs. Takata the leadership of Reiki.  He gathered all the Reiki Masters to a gathering, announced Mrs. Takata to be the leader of Reiki, and then announced he would kill his physical body through bursting three blood vessels.  And as he continued speaking and lecturing those blood vessels burst and he died.

Mrs. Takata returned to Hawaii and continued using and teaching Reiki.  Eventually she moved to California, using and teaching Reiki there as well.   She did not teach other masters until 1975, and before her own death in 1980 she trained 22 Reiki Masters.
