Rosh Hashana 5763
So, what do math and Rosh Hashana, the Jewish New Year, have in common. On this day, Jews are supposed to do a cheshbon hanefesh. This literally means \”accounting of the soul.\” We count up and categorize all the actions we\’ve taken, and all the thoughts we\’ve had during the year: How many good? How many bad? How many generous? How many selfish? How many useful? How many just a waste of time? Then we decide which actions and thoughts we want to repeat and which we will throw away.
