Some other references:
Al-Ghazali says: 'the Opener' is the One by Whose providence whatever is closed is opened. He refers to this quote from the holy Qur'an (35:2).
'What Allah out of His Mercy Doth bestow on mankind None can withold: What He doth withold, None can grant, Apart from Him: And He is the Exalted In Power, full of Wisdom.'
He counsels us to yearn to reach a point where the divine mysteries are 'opened by our speech' and where, by our knowledge, we may make things clear to others which are not clear to them.

The true Sufi Sheykhs have the power to transform the understanding of the one with a receptive heart in a moment, sometimes through the medium of a story or sometimes by a look or by some other means.

The Opener He Who Opens all Things
Al-Fattah (Al-Fattaah) Qur'an 34:26
Say: our Lord will gather us Together and will in the end Decide the matter between us (And you) in truth and justice: And He is the One to decide, The One Who knows all.
