Communicating with the Sword

'' “A sword is the guardian of my heart and my soul. By opening my heart and listening to the sound of the sword and act as its master then we can claim ourselves as true samurai” ''

This is the natural progression of being able to wield a weapon as if it were an extension of oneself. Communicating with their weapon means that a wielder knows their weapon’s spirit very closely and vice versa. The connection is very deep, though in the beginning the connection is one sided with the wielder being unable to fully hear the spirit communicating with them. The spirit of the weapon is both a reflection of a wielder's soul and power, and a sentient being unto itself. The samurai uses their weapon in battle as a reflection of their heart. When released, they can display a vibrant power, and shine as brightly as the Lupus Star. They are one with the samurai, and they share a samurai's conviction. Communicating with a weapon can only be done if the weapon is within the samurai’s grasp for quite some time. A new weapon or one that be longs to another warrior cannot be communicated with. This link is also permanent as  Oda Nobunaga  showed. Even though he was in an entirely different body and it had been about 24 years since he last wielded it. Nobunaga  was still able to talk to Samonji. Julian integrated thing into his swordsmithing technique which is why his weapons are so powerful. As a sword smith he is able to communicate with any weapon created by him or his pupil Muramasa. Muramasa further refined this technique to put actual souls into his Four Demon Blades
