We all long for [Eden], and we are constantly glimpsing it: our whole nature at its best and least corrupted, its gentlest and most humane, is still soaked with the sense of ‘exile’. If you come to think of it, your (very just) horror at the stupid murder of the hawk, and your obstinate memory of this ‘home’ of yours in an idyllic hour (when often there is an illusion of the stay of time and decay and a sense of gentle peace) are derived from Eden.J.R.R. Tolkien, The Letters of J.R.R. Tolkien, 110.
“it is difficult to define hiraeth, but to me it means the consciousness of man being out of his home area and that which is dear to him. That is why it can be felt even among a host of peoples amidst nature’s beauty; like a Christian yearning for heaven.”D. Martyn Lloyd Jones
