Kenichi Matsumoto tried various meditation techniques, healing practices, therapies and other methods in the past in order to resolve anxiety in general. At one point, he realized that his anxiety stemmed from fear of death and not knowing what would happen after death. He then began searching for Truth and satori. Although he had certain experiences and insights through his previous practices, they only satisfied him temporarily and he was returned to searching for Truth.
After exhausting everything he could think of, one day Matsumoto encountered a book by one of the most prominent Zen masters in modern Japan. Matsumoto could see that Zen would put an end to his quest, and he began practicing diligently.
He sat whenever and wherever possible until one night, with "click" (noise made by a clock), "what is already clear (Truth)" was revealed.
In his teachings, Matsumoto aims to support his students so that they become able to sit correctly as quickly and efficiently as possible. He states: "once one learns to sit correctly, all one has to do is continue sitting. Truth will be revealed for anyone as long as one sits."
Matsumoto often says: "I am now able to tell you about Zen (Truth) because Truth was revealed for me. It's only that Truth was revealed to me before you. So my role is like a guide who tells you 'if you do this, Truth will be revealed,' and 'if you do that, it will not be revealed.'"
