" Isaac entered. Reb Alter raised his head and said, Welcome, Itzikl, a guest who comes in time. I was just thinking about you and here you come. You see, Itzikl, there is power in the thought of a Jew, that it draws to us those who are dear to our heart, like a magnet drawing iron to it. And if we purified our thoughts we would do wonders. And on that, Itzikl, I have a tremendous argument, as the Bible says, I thought on my ways and turned my feet unto thy testimonies, that is, if a person thinks cunningly on his ways, in the end he returns his feet to Torah.
