It is impossible that this gnosis resulting in the heart should be achieved by man for any other purpose than to obey God, love Him, and worship Him. This gnosis should be sought for the sake of God, not for any other reason whatsoever, unlike the remaining external acts of devotion, which can be performed for other worldly interests, such as hypocrisy, praise, and commendation.
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
