Resuming the talk of abstraction in combat, we want now to define, in relation to the practice of fighting, what does it mean (at its most extreme level).
Bearing in mind that these are just general guidelines and examples let's see, in 6DKF, what does it mean to abstract the clash:
Stay in a highly responsive state but with a meditative and detached mental attitude; on the battlefield we are alone with ourselves, we are against ourselves, others stop worrying us
Understand that everything is part of a one that we can use without hesitation and limitlessly to reach our goals
Reduce any entity of the fight scenario (a room, a ring, a forest, etc.) to a set of elements that move and work according to well-defined rules imposed by physics (so for humans, inanimate objects, weapons, etc.)
Analyze the opponents as inert targets with a range of instruments and possible movements limited by the psychophysical condition / position in which they are
Do not worry (if reasonable) about what the adversary is probably thinking to do but rather concentrate on anything that is actually in the condition of doing (mentally, physically, etc.); in this way the 90% of fake / tricks are almost useless (that's the reason why in 6DKF we train to handle more unpredictable, fast, changing and "evanescent" targets of a human being)
Understand not only the general human mechanics (eg. the difference between a movement that is so evolute that it cannot be "reversible" by one who can hide another one) but also the personal mechanics of opponents (recognizing emotions, damages, repetitions, errors, sequences, involuntary signals, tactical settings, skills, etc.)
Eliminate any spontaneous human emotion (desire for revenge, anger, frustration, fear, hurry, etc.) or feeling (pain, fatigue, malaise, etc.) as if we were struggling in a virtual, ethereal, mental environment (eg. the opponent speaks, we do not ear him)
Invoke in our favor every possible emotion / sensation to give us energy, strength, resistance, determination or courage (firmness, decision, enthusiasm, etc.) but without being its victim (one of the most impenetrable states of a warrior is the one where he is so detached from the struggle to sincerely feel piety for his enemy)
Quoting Masaaki Hatsumi, playing serenely with the opponent as if we were not risking anything (not our life, not defeating, nothing at all); we must have a relaxed, enthusiastic but patient attitude
Feel that we are so close to our element, so mastering our instruments to live combat as our natural environment
Be 100% there, do not want the fight and at the same time do not want to avoid it (it's not about feel pleasure or to desire the clash but to deal with it intensely without being involved in its rules)
Choose to have nothing to lose (we are made of matter, energy, we are at the same time continuous revolution and eternal staticity); the greatest expression of a "zen warrior" is to remain completely indifferent to the idea of victory or defeat, life or death, without desires
This state of "mental absence" (if true) is not only difficult to achieve but is also very dangerous and it has to be used only in situations where life is really in danger (it is possible to fight very well even without access completely to this state of "trance").
With this mechanism in action the mind is completely emptied of thoughts (doubts, disturbances, inhibitory brakes, ethical judgments, etc.) and the body released by its the inbiting brakes (work of antagonistic muscles, Qi restraints, etc.), each part of our body is focused solely on combat and will continue to move relentlessly by stopping only after annihilating (or being annihilated by) who opposes it.
There is more to say but for now we stop here, then we will deepen the subject further.
