The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from De Profundis by Oscar Wilde:

that like a purple thread runs through the texture of DORIAN GRAY; in THE CRITIC AS ARTIST it is set forth in many colours; in THE SOUL OF MAN it is written down, and in letters too easy to read; it is one of the refrains whose recurring MOTIFS make SALOME so like a piece of music and bind it together as a ballad; in the prose poem of the man who from the bronze of the image of the 'Pleasure that liveth for a moment' has to make the image of the 'Sorrow that abideth for ever' it is incarnate. It could not have been otherwise. At every single moment of one's life one is what one is going to be no less than what one has been. Art is a symbol, because man is a symbol.
