In meditation, nothing disturbs you, and endless thoughts sweep from one side to the other as bullets fly overhead during combat, but they do not hurt you and you serenely rush into battle when the insight that triggers your spontaneous cries of "Eureka".
At this moment, the points of contact with the Truth are born, when the spirit is moving towards achieving its goals, as a soldier of the Soviet army ran ahead and shouted "For the Motherland! For Stalin")).
Zen is the philosophical basis of martial arts in Japan))) and today it is adapted to the modern militant reality))) you just change external form, and ritual worship of the sword is transferred to you on AK-47 and other toys))) Satori - enlightenment helps you realize that you are finally shooting well))) and the collection of weapons is perceived as a delicate process of meditation))) concentration, concentration. Thoughts turn into a stream of a river and no longer disturb the mind, they are like empty cartridges that are fired from pistols, but in no way do harm and have no effect.
