Why was the world created? Why do we have to go through this life fraught with challenges? We, by our very existence, create a conflict for G-d; we interfere with His G-dly existence. By lowering our concentration on ourselves and focusing intensely on G-d alone, we will come to know Him, experientially. We will feel the existence of G-d through ourselves. It is in your hands, and your hands only, to adjust the presence or absence of shechina in this world.
