Chasidut zu Schemot 32:18

This is the entire matter. When that which transpires within man is hidden and not felt, it serves create a chasm between man and himself. He does not know himself and is not aware of what is going on inside of him. The soul of the ordinary man does not cease to shake, quiver, and cry out over its lowly status, its wounds, and its pains that it suffers due to man’s foolish actions and thoughts. And man does not feel the pain of his own soul because he does not stop to listen to its painful cries that resound within him, because it is the way of man to constantly be drawn to that which is external to him, perceiving things form the outside world, whether necessary or useless. Though man will easily take interest at something that takes place on the other side of the world, he barely pays attention to the uproar within his own soul. It could be that he even feels the pain of his soul, it is just that at the time that he feels it his desires and thoughts are sunk in the rubbish of worldly matters, and therefore the sobbing of his soul is mixed together with the sounds of worldly vanity.⁴⁹See Shemos 32:18, “it is the voice of those that sing that I hear.” This may be compared to a man who is sleeping, and a mosquito comes and bites him on the forehead. If he is a merchant, he will dream that a bundle of merchandise fell on his forehead and wounded him. If he is a tailor, he will dream that his needle pierced his forehead. Everyone sees his dream in the garment of his own thoughts.
