Sanchin (three battles) is referred to as the oldest exercise form of karate, which takes three battles of body, energy and mind.
Three battles mean three disciplines that form a basic exercise assignment to produce a result. It is actually an equation (meditation) of three unknowns that is solved by exercise. It begins gradually from form (body), which reveals functional content (energy) that reveals the mental nature (mind). Finally, the sum of all members reveals the result of consciousness and emptiness.
In order not to bother you, we have explained the nature and practice of Sanchin. However, even after this theoretical explanation, there are still many practical secrets left to every practitioner and many interesting exercises he has to master.
Sanchin is not just the name of the oldest form of karate exercise, but it is the principle of all psychosomatic exercises in all its various eastern and western variations (karate, taichi, sport, etc.).
The Western mentality is unable to do something without knowing the purpose. But even if the purpose is known, it is practically not doing so, because the power to practice has been exhausted by a theoretical understanding that is generally considered to be sufficient.
The Eastern mentality is different. This is able to practice without a sense of purpose and reason. It works in anticipation of sudden surprises or enlightenment. The results of the Eastern practice can be diametrically different from the Western exercise procedure.
The Western (male) and Eastern (female) mentality are two polar functions of our mind and consciousness. Western civilized people have a greatly suppressed Eastern mind. One of the main purposes of the right method of training is to establish a balance between the external and internal minds.
