There is a world of difference between an inference and a feeling. You can reason that the universe is a unity without feeling it to be so. You can establish the theory that your body is a movement in an unbroken process which includes all suns and stars, and yet continue to feel separate and lonely. For the feeling will not correspond to the theory until you have also discovered the unity of inner experience. Despite all theories, you will feel that you are isolated from life so long as you are divided within. 

But you will cease to feel isolated when you recognize, for example, that you do not have a sensation of the sky: you are that sensation. For all purposes of feeling, your sensation of the sky is the sky, and there is no “you” apart from what you sense, feel, and know.

The sense of unity with the “All” is not, however, a nebulous state of mind, a sort of trance, in which all form and distinction is abolished, as if man and the universe merged into a luminous mist of pale mauve. Just as process and form, energy and matter, myself and experience, are names for, and ways of looking at, the same thing — so one and many, unity and multiplicity, identity and difference, are not mutually exclusive opposites: they are each other, much as the body is its various organs. To discover that the many are the one, and that the one is the many, is to realize that both are words and noises representing what is at once obvious to sense and feeling, and an enigma to logic and description.

When you really understand that you are what you see and know, you do not run around the countryside thinking, “I am all this.” There is simply “all this.”
