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!

Invoking removes darkness and brings forth radiant lights.

He 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.

The realization of 'La ilaha illa Allah' is one of the states of the heart that can be neither expressed by the tongue nor thought out by the mind.

Nothing is difficult, if you seek it through your Lord; nothing is easy, if you seek it through your self.

Know that the science of unveiling has no end to it, for it consists in the journey of the intellect in the stations of Majesty, Beauty, Sublimeness, Grandeur, and Holiness. . . . He to whom the mysteries of La ilaha illa'llah are revealed draws near to God, and his worship of God becomes sincere. He does not turn to anyone but to Him, nor does he have hope in or fear other than Him, nor does he see harm or benefit except as coming from Him. He abandons whosoever is not He and rids himself of inward and outward associationism (shirk).

If you want a glory that does not vanish, then do not glory in a glory that vanishes
