I think you're on the right track here, but the way to truly understand this is not by coming to some conceptual conclusion, but to look at things in such a way that you can see that the world as you know it arises in the mind, in this way you can see through language and concepts in general. There are some good points to reflect on, just ask the right question and look for the answer through seeing, not through conceptual proliferation. One thing you could look at is how once you create a thing you also create a self in relation to that thing and then you could ask yourself what happens if the mind doesn't give rise to a subject/object dichotomy. The more clever you are at asking the right questions the deeper you can look at this issue, but the only way you'll ever truly grasp the profundity of this topic is by seeing for yourself. Anyway, I hope that helps and if not then feel free to disregard it.
