Invoking brings the heart closer to the hereafter and keeps the world away from the heart, even though the world is around it. Invoking warns the heedless heart to abandon its pleasures and deceptions.
Ibn Ata AllahHe whose wealth or children distract him from remembering God is lost; but the one who remembers God experiences delights sweeter than the pleasure of food and drink.
Ibn Ata AllahInvoking 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 Allah
