George Santayana - "Have patience; it is fit that in this wise" lyrics

Have patience; it is fit that in this wise The spirit purge away its proper dross. No endless fever doth thy watches toss, For by excess of evil, evil dies. Soon shall the faint world melt before thine eyes, And, all life's losses cancelled by life's loss, Thou shalt lay down all burdens on thy cross, And be that day with God in Paradise. Have patience; for a long eternity No summons woke thee from thy happy sleep; For love of God one vigil thou canst keep And add thy drop of sorrow to the sea. Having known grief, all will be well with thee, Ay, and thy second slumber will be deep.
