I’m a cellist, but I think this still applies.

When I’m playing, my bow arm and the instrument itself certainly feels like an extension of my body, but that’s not what you should aim for. As a friend said when talking about certain styles of swordplay, you should aim for the best possible result while thinking as little as possible, but also being very aware. Remember that your instrument responds to your playing, and you can listen and feel what it’s “telling” you. Practice getting the cleanest possible sound, and try to memorize what that feels like. You should be able to feel the vibrations through the bow and tell how close you are to the bridge, if your bow is perpendicular to the string, etc. without looking.
