If your knowledge teaches you not to rise above human weakness and misery and lead your fellow man on the right path, you are indeed a man of little worth and will remain such till Judgment Day.
I am the lover's gift; I am the wedding wreath; I am the memory of a moment of happiness; I am the last gift of the living to the dead; I am a part of joy and a part of sorrow.
When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight. Some of you say, "Joy is greater than sorrow," and others say, "Nay, sorrow is the greater." But I say unto you, they are inseparable. Together they come, and when one sits alone with you at your board, remember that the other is asleep upon your bed. Verily you are suspended like scales between your sorrow and your joy.
