Seek for no meaning in it; it has none. What meaning is there in pain and pleasure? They are twins; that is all we know. Seek no meaning in anything you see here. Images, ideas, flashes of purpose will peer out in all our ways and deeds, but there is no intention here below. Is there any intention anywhere?

Pleasure is oft a visitant; but pain / Clings cruelly to us.

...when pain is over, the remembrance of it often becomes a pleasure.

Face your life, its pain, its pleasure, leave no path untaken.

Of four infernal rivers that disgorge/ Into the burning Lake their baleful streams;/Abhorred Styx the flood of deadly hate,/Sad Acheron of sorrow, black and deep;/Cocytus, nam'd of lamentation loud/ Heard on the rueful stream; fierce Phlegethon/ Whose waves of torrent fire inflame with rage./ Far off from these a slow and silent stream,/ Lethe the River of Oblivion rolls/ Her wat'ry Labyrinth whereof who drinks,/ Forthwith his former state and being forgets,/ Forgets both joy and grief, pleasure and pain.
