Exactly! The existence of entities and their natures are entirely dependent on our perceptions. We might even go so far as to say that the mind is the center of the universe - everything revolves around it. The Sun might as well be revolving around the earth, because that is what we experience and experience is all we have as reality - what does truth mean if we will never be able to experience it? This is the reason for the utter subjectivity of truth - what we experience is truely reality, whether we like it or not. It's tantamount to telling someone who is color blind that there are actually colors, but a color blind person never experiences color - to him the world is without color - that is his reality - his truth.
