All decisions come from the heart. The mind is never decisive, it cannot be. If you want to decide through the mind, you never can. And I am not talking about great things like enlightenment and the existence of God or the existence of life after death. I am not talking about great things, just small things -- whether to purchase this soap or that, or which toothpaste -- and you will find the same difficulty. Mind is fragmentary, divided.
Hence my consistent insistence that you get out of the mind and start living. The mind only thinks and never lives. It thinks beautiful thoughts, but they are thoughts all the same, just dreams.
