Sufis say, pray in such a way that nobody knows. Why? For the simple reason that ego is very cunning. It wants to brag; it wants to brag even about religion, about spirituality, about prayer, about meditation. It wants to brag; it does not matter what it brags about. It will brag about money, it will brag about meditation, it will brag about power, it will brag about prayer. The ego wants to brag: “I am doing something special, something great, something extraordinary. Don’t think that I am nobody — I am somebody!”
