Zanshin teaches us to be one with our surroundings and to be keen of mind even in the face of fear. Zanshin is being aware of all that surrounds you but not being focused on one thing. It can be applied to many concepts... Fighting, living, School, nature and much more.
so it's like Seeing every thing but seeing nothing just being a a concentrated state
Similar to what you're describing, but Zanshin is even more than this. I don't know it it relates to most, but when you're in a state of hyper-awareness during a fight, when you hit that "zone" and can sense what an opponent is going to do before they even know or when you've got your back to the enemy but they still can't get the drop on you even though they're being perfectly stealthy, that is Zanshin. Modern science hypothesizes that when you're deep in a meditative state, the body's awareness of electrical fields and its interpretation of the signals from your senses reaches a heightened state allowing you to decipher the motives and intentions of others from the slightest of whispers and body language.
