The knowing heart is receptive to the intelligence of Being and is guided by Being. When the heart is awakened and purified, it establishes a connection to Spirit; our finest and noblest capacities are unlocked, our sacred humanness is revealed. What it comes down to, the distillation of all wisdoms, is this: we can rejoin our isolated wills with Love's Will through the knowing of the heart.
People have always wondered at the saints, that they are able to walk around serene, whatever happens. But that is because they can choose where they'll be. They don't have to be angry. You see the difference between having scattered emotions and having a fully vibrating, controlled emotional body. This body is made from energy created from choice, from the effort involved in making choices. But it is necessary to practice; then something is possible.
