Yes, but the shift for most people from conceptual mode to union does not occur 'just like that'. Maya, social indoctrination, and our biologies are powerful barriers to such a shift. But when the shift does occur, what we thought was the case, turns out not to be the case. Our view is radically transformed right before our eyes. So even though union is already the case, as you pointed out, unless we experience this transformation so that we can see things as they actually are, we will continue to be deluded, a condition reinforced by the rational mind. So, you see, contrary to what you have been saying, it DOES matter, because deluded thinking eventually leads to some sort of suffering. At the very least, we are kept ignorant, pursuing paths that seem right, but lead only to more suffering, such as the paths of Security, Sensation, and Power, paths pursued by most of mankind.
