The Edinburgh Lectures on Mental Science (Electronic book text)

From this standpoint we see that all is Life and all is Good, and that Nature, from her clearly visible surface to her most arcane depths, is one vast storehouse of life and good entirely devoted to our individual use. We have the key to all her treasures, and we can now apply our knowledge of the law of being without entering into all those details which are only needed for purposes of study, and doing so we find it results in our having acquired the consciousness of our oneness with the whole. This is the great secret: and when we have once fathomed it we can enjoy our possession of the whole, or of any part of it, because by our recognition we have made it, and can increasingly make it, our own.
