What is the difference between munen and mushin? These concepts outline the ideal mental state for the bushi, or warrior of Japan. Attaining either munen or mushin is not overly complicated, yet it can be a difficult subject to discuss. Mushin is integral to the physical acts, tactics, and strategies of bugei. Munen muso is a larger concept for the development of the bugeisha.
Allow me to offer my non-scholarly breakdown of these words. Mu 無 means nothing. I don't want to get into an Abbott and Costello routine here, but yes mu doesn't mean anything.
"What does mu mean?"
"It has to mean something, Abbott."
"It means nothing, Lou!"
Mu once had its meaning in the pictograph for destroying a forest. But its early writing also showed what was possibly a priest giving some sacred dancing and holy rites for a fallen person. Death representing the nothingness. The emptiness and space, rather than the absence of something is a metaphor for what the open and unobstructed mind of munen and mushin represent.
Nen 念 is a word meaning thought in the vein of a desire or a thirst for something. We can get a very Buddhist construct when we put mu and nen together. Munen deals with the idea of having no sensual desire or worldly thoughts. No desire to be nor a wish not to be. No desire to satiate our many thirsts of the eye, nose, mouth, skin, etc. Munen is an ultimate state of mind where one is not being pulled in the directions lead by our desires. Munen muso becomes a phrase meaning no desire and no thought. The mind is in a quite advanced enlightened stage with munen. This type of stage is something cultivated over longer periods of time. It is quite different from mushin. It might be helpful to consider munen as the larger aspect of 'no-thought'.
The phrase, no-mind or no-thought is attributed to the samurai warriors and Buddhist monks of Japan. Munen-muso is not exactly a battle friendly state of mind. A mind imbued with munen is unrestricted by the fetters of ignorance, anger, fear, belief in the self, desire for existence and non-existence, and sense desires, to name some.
TAKE IT TO HEART
Shin 心 means mind or spirit. Our mental faculties are represented by shin. Through meditation and contemplation, we can cultivate certain states of mind that lead to mushin no shin. The state of no-mind is the mind free from calculating and clinging. This is the functioning state of mind that leads to munen. It is mushin that is useful to the warrior directly involved in combat or the martial artist. It is a neurologically opened state where there is no scheming or planning. Some of us have experienced this when we knock something off the table and without thinking we catch it. The state of mushin is a very natural part of our lives. It is not a mystical or unattainable state of mind. If you have ever "lost yourself" in playing a musical instrument or singing, or chanting then you have achieved the mushin. If you have ever experienced that open flowing moment while playing baseball, jogging, or even mowing the lawn, then you have achieved mushin.
Mushin is different from munen. You can be a person full of greed and anger for example but still attain mushin. Mushin is a temporary state. Munen is a state of mind that undergoes a permanent transformation. When someone rids themselves of greed, they have understood its origins, and its how it arises. When it is understood and triumphed greed does not return. Mushin can be achieved by anyone, however, munen requires a lot of work and many years of practice. Munen is the ultimate goal.
During bujutsu keiko or martial arts training mushin is something achieved naturally when the practitioner has attained enough general movement memory to perform techniques without forethought. In arts like kenjutsu, the student is pushed into dealing with the sword of uchidachi, therefore mushin can be triggered somewhat more profoundly sooner than the solo art of iaijutsu. The absence of conscious planning and scheming is where mushin blossoms. Letting go of ego-driven inner dialogue and planning will allow the state of no-mind to flourish. It is why reaction times seem so fast. We have the somatic aspect of speed, how quickly limbs can move based on the condition of our ligaments, tendons, and muscles, but we also have the speed potential at which those limbs can react. Mushin opens the neurological latent speed by bypassing 'us'. The 'I am going to do this or that' part of us. It just isn't needed, and in mushin, it isn't there. That is why its so valu¥able to the warrior or martial artist. It is a more or less pure reaction, an open stream of light through a window. It doesn't pass a filter, the sunlight just shines onto the floor unobstructed and unchanged. We do not have to fiddle with blinds or shades and draw them open to get the sunlight into the room. In mushin, we have removed the shades and filters.
In the end, intellectualizing all of this is a danger and leads no one closer to understanding it. One should not set out to achieve these states explicitly, but to slowly focus and hone one's skills during keiko or shugyo. These states can best be understood by attaining them in our practice.
