"Passion has sensuality, sexuality, feelings, emotions. These are all passions. Line of them. They are the purpose of life. They move the life. But they are not the steering of life and they are not the brakes of life and if you have a best transmission, best transmission okay, full tank of gas, fine tires, good engine, all set, you don't have a steering wheel and don't have brakes, I'll see where you end up. You understand what I am saying? A person who does not have compassion in life is not worthy to be called a human being. We call him in scripture double-leg animal. We don't call it even two-leg animal. Because such person even cannot make distinction, which leg is left and which leg is right. Passion hei na, passion tho blind hei, passion tho force hei. Passion is like gas. You can work it out. Gas, you can cook your meals, you can heat your room, you can... but it can totally blow up your house too." -Yogi Bhajan
