Mushin and fudoshin get described with some of the most contradictory language around. Mushin is written 無心, and literally translates as “no mind.” Fudoshin is written “不動心” which is probably best translated as “immovable mind,” but which Takuan describes by saying:
Although wisdom is described as immovable, this does not signify any insentient thing, like wood or stone. It moves as the mind is wont to move: forward or back, to the left, to the right, in the ten directions and to the eight points; and the mind that does not stop at all is called immovable wisdom.
Takuan Soho, The Unfettered Mind. William Scott Wilson translation
A mind that is no mind, and and immovable mind that does not stop at all. This kind of language makes no sense at all. At least it didn’t for my first decade or two of budo training. Mushin and fudoshin are mental states that are developed through hours and hours of training. Like most things having to do with our minds, these are complicated.
One of the first complications is that character for mind used in both mushin 無心 and fudoshin 不動心 that I pointed out at the beginning. The character 心 (pronounced “coe-coe-roe” and written kokoro in romaji) contains characteristics that in the Western tradition have been split in two. In English we talk about the mind as the seat of logic and intellect, and we talk about the heart as the seat of the emotions.
The Japanese don’t make the mistake of trying to separate the intellect and the emotions. They recognize that these are not separate things, but two parts of a greater whole. Intellect informs emotions, and emotions affect intellect. This should be obvious, but our cultural inheritance obscures it. When we talk about mushin and fudoshin though, we are definitely talking about both the intellectual and the emotional parts of us. We just don’t have a word in English that encompasses all of this.
Mushin means “no mind.” That’s pretty unimaginable. No mind? Isn’t that like being in a coma? No, it’s not, and that’s the problem I have with the term mushin. It’s not about being mindless. It may be closer to the way people are using the term “mindful” lately, but that’s not a descriptor either. Mushin has several layers to it, but I think it can be understood, even when you still have thousands of hours of training to go before you can consistently achieve it.
Mushin starts, not with no mind, but with a calm, clear mind that doesn’t impose itself. That’s the first step. Let your mind be quiet so it’s not imposing assumptions on the situation, and not trying to force any particular course. If you are making assumptions about your opponent or if you insist on following a particular course in the middle of a fight, you’re in trouble long before you close the ma’ai.
