Invoking the letters of God's Name without presence of mind is invocation of the tongue; invoking with presence of mind is invocation of the heart; and invoking with an absence of self-awareness because of absorption in the Invoked is the invocation of the Self - this is the hidden invocation!
Ibn Ata AllahThe ambition of the spiritual traveller never wants to stop with what it has been shown save that the voices of reality call to him, "what you seek is ahead of you.
Ibn Ata AllahIf He opens a door for you, thereby making Himself known, pay no heed if your do not measure up to this. For, in truth, He has not opened if for you but out of a desire to make Himself known to you. Do you not know that He is the one who presented the knowledge of Himself to you, whereas you are the one who presented Him with deeds? What a difference between what He brings to you and what you present to Him!
Ibn Ata AllahI know of nothing more useful to you than four matters: surrender to Allah, to humbly entreat Him, to think the best of Him, and to perpetually renew your repentance to Him, even if you should repeat as in seventy times in a day.
Ibn Ata AllahA sign of the death of the heart: lack of sadness about beneficial actions you have missed, and lack of regret about your mistakes.
Ibn Ata AllahLet your invocation be the all-embracing Name, which is Allah, Allah, Allah, or if you so wish, Huwa, Huwa, Huwa; and do not violate this remembrance. Be careful lest your tongue pronounce it while other-than-He is in your heart. Let your heart be the one who utters, and your ear the one who is attentive to this invocation until the 'speaker' emanates from your Self (sirr). When you feel the emergence of the Speaker within you through the invocation, do not abandon the spiritual condition wherein you find yourself.
Ibn Ata Allah
