All things are different forms of stored energy. This energy steps through different phases altered by the elements, the sun, and sometimes, man. Each bow follows a different path, so it's energy level, and properties are different. Shooting is about how we use this energy, how we interprete it, how we harness it, how we interact with it. When all that lines up with our own energy force, we have one sweet shooting bow. Sometimes we think the bow needs to conform to our energy pattern, when it's really the other way around. It's what you put into making the connection. The wood bow doesn't have a 'soul', but it's definitely talking to you.
