Light (1919), Ch. XXIII - Face To Face
Context: What is there within us to-night? What is this sound of wings? Are our eyes opening as fast as night falls? Formerly, we had the sensual lovers' animal dread of nothingness; but to-day, the simplest and richest proof of our love is that the supreme meaning of death to us is — leaving each other.
And the bond of the flesh — neither are we afraid to think and speak of that, saying that we were so joined together that we knew each other completely, that our bodies have searched each other. This memory, this brand in the flesh, has its profound value; and the preference which reciprocally graces two beings like ourselves is made of all that they have and all that they had.
I stand up in front of Marie — already almost a convert — and I tremble and totter, so much is my heart my master: —
"Truth is more beautiful than dreams, you see."
