The Treasure of Love is rare

In this world there are innumerable treasures. We are well versed in knowledge and philosophy, but the state of being in love with the Beloved, expressed by painful sighs and tears because of separation from Him at night, is the lot of a rare few. 

Hafiz says:

I have innumerable treasures of knowledge and of intellect but, alas, I cannot write the story of the tears shed in separation at night, nor of the sighs of longing for my Beloved.
