I made intentional difficulty in understanding because I wanted to share it only with those who genuinely wanted to know and understood my intention. I wanted to adhere to this principle because, while I don't ask for any return, I wanted people to recognise that it's something I discovered.
So, I do apologise for making it intentionally unclear.
In this video, I explain in my own words the process of discovery and why I decided to share it for free, albeit clumsily! I believe it's effective, and I want as many people as possible to try it, even if it's just one person. I am talking in Japanese but the English subtitles should appear.
