Being is the eternal, ever-present One Life beyond the myriad forms of life that are subject to birth and death. However, Being is not only beyond but also deep within every form as its innermost invisible and indestructible essence. This means that it is accessible to you now as your own deepest self, your true nature. But don't seek to grasp it with your mind. Don't try to understand it. You can know it only when the mind is still. When you are present, when your attention is fully and intensely in the Now, Being can be felt, but it can never be understood mentally. To regain awareness of Being and to abide in that state of "feeling-realization" is enlightenment.
— Eckhart Tolle
