The brain is the past and the Heart is the future. Only in the united consciousness, free of the self, can we accept the teachings of the Heart. We cannot journey into the future without letting go of the past. There is a summons to a unity of consciousness everywhere, because this is the simplest introduction into the life of the Heart. It is not the physical heart that pumps blood that is referred to here, but the awakening of the mystical Spiritual Heart that allows us to feel altruistic love. To activate the mystical Heart we need to embrace the Subtle World, the World of Spirit.
