A true warrior doesn't need anything of that to see, only the understanding of someone that had lost any mean of physical perception. Time does not truly exist it is a trick of the mind that adds motion and depth to what would otherwise be empty space without variation or rhythm. Matter is energy that vibrates like a bell and a rhythm of its own. When locked in the form of a stone it becomes a network of interlacing patterns. Think of a diamond that is the hardest of all substances, But within its crystal matrix lays a hidden flaw that can be found with the mind, not the eye. The eyes deceive and the words of men are lies, but the heart shall never lie, and in that truth we find the path that leads us to the point of awakening. The Shingan doesn’t use the ears, nor any other physical sense
