Develop intuitive judgement and understanding for everything. - Miyamoto Musashi

per guadagnarsi la vita ogni artigiano deve curare con attenzione la manutenzione dei propri attrezzi e saperli usare con la massima abilità.

"To know the times" means to know the enemy's disposition in battle. Is is flourishing or waning? By observing the spirit of the enemy's men and getting the best position, you can work out the enemy's disposition and move your men accordingly.

I feel confident in this assumption because between myself and my longtime students, often things happen that seem like telepathy, but it is more truthfully a relationship that has reached a maturity where words are not necessary for full communication. A quick nod in the direction of some equipment in the room and the student who has been there for years will understand it to mean, “Go get that.” The unspoken statement in that question is surmised from the context of the lesson. I don’t need to tell them precisely which piece of equipment to bring, because they already know what I am asking for. They have been around long enough to be able to add two and two together. To a beginner, it may seem like a superpower, but it is just relationship. We could and should assume the same holds true here. Not every detail needed to be spelled out.
