GOD and Desires
In God’s world, we are not the only alone beings, there are other people too. But Yes, God is absent in our own created worlds. Because we are driven by desires. And God is one who halts desire. Therefore, we have removed God from our individual worlds for our wills. And that removal has condensed our worlds to individuality and has made our only individual physical beings the central focus of those individual worlds. We are alone in our own created worlds. It is like a bubble around each of us that keep us at distance from others, and so we feel alone even if we are in hordes.
