Overheard

It is a great thing to hear music from a holy person playing on an instrument for the sake of Heaven, because through this, false fantasies are dismissed, the spirit of depression is dispelled, and the person merits happiness. Through this the memory is preserved, that is, the memory of the World to Come, and a person is able to understand the hints that Hashem is constantly hinting to him every day. Furthermore, through this a person can reach the level of the spirit of prophecy and Divine Inspiration, and he will be able to pour out his heart like water before Hashem.

"People walk around sad because they don’t know what to do with their future. You have this minute right now. What are you doing with it? The difference between sadness and joy is very simple. Sadness always tells you : ‘Oy vey! What are you going to do in ten minutes? What will you do ten years from now?’ if you are really filled with joy for one minute, then you will know what to do the next minute also. What is God giving you? He is giving you this minute. He hasn’t given tomorrow. Of course, I don’t know what to do tomorrow, because I didn’t receive it yet. Sadness is very much concerned with what I don’t have, and I really don’t have tomorrow
yet. The truth is, I am always standing before nothingness, because I am nonexistent yet for the next minute. I’m not here yet. Time isn’t there. The world isn’t there. The world is here… right now!"

(Reb Shlomo Carlebach)
