Only in the agony of parting do we look into the depths of love. George Eliot
The pain of parting is nothing to the joy of meeting again. Charles Dickens
It was among farmers and potato diggers and old men in workhouses and beggars at my own door that I found what was beyond these and yet farther beyond that drawingroom poet of my childhood in the expression of love, and grief, and the pain of parting, that are the disclosure of the individual soul. Lady Gregory
The logs of wood which move down the river together Are driven apart by every wave. Such inevitable parting Should not be the cause of misery. Nagarjuna
They who go Feel not the pain of parting; it is they Who stay behind that suffer. Henry Wadsworth Longfellow
