“As we suffer these misfortunes we must remember that the Prophets of God Themselves were not immune from these things which men suffer. They knew sorrow, illness and pain too. They rose above these things through Their spirits, and that is what we must try and do too, when afflicted. The troubles of this world pass, and what we have left is what we have made of our souls, so it is to this we must look to becoming more spiritual, drawing nearer to God, no matter what our human minds and bodies go through.” 

Shoghi Effendi, Lights of Guidance, p. 297
