Sufi Aphorisms - the Kitab-al-Hikam

If you want the door of hope be opened for you,

then consider what comes to you from your Lord,

but if you want the door of sadness be opened for you,

then consider what goes to Him from you.

- "The Hikam" Sufi Aphorisms

by Ibn Ata'Allah al Iskandari

Late 13th Century C.E.
