Susan

“So you're in love with her?' she went on.

A word again ... When the minds have learnt to mingle, when no thought is wholly one's own, and each has taken too much of the other ever to be entirely himself alone; when one has reached the beginning of seeing with a single eye, loving with a single heart, enjoying with a single joy; when there can be moments of identity and nothing is separate save bodies that long for one another ... When there is that, where is the word? There is only the inadequacy of the word that exists.

'We love one another,' I said.”
― John Wyndham, The Chrysalids
