Hence, the Will by itself is manifestation of the Essence and other existents have been created through its means. We don’t however intend to give here the proof of this sublime matter. The devotee who understands this matter on the plane of theory and metaphysical proof, knows that his own being, as well as his worship, knowledge, will, heart, the actions of his heart, and his inward and outward being all of them are present before His Sanctity or, rather, they are presence itself. Should the pen of his intellect inscribe this truth on the tablet of his heart and should the heart attain conviction in this certain, axiomatic premise by the means of theoretical and practical exercises, he will obtain attention of the heart to the revelations on the plane of faith.
– Imam al-Nawawi: ‘Forty Hadith, An Exposition – Twenty-Seventh Hadith: Prayer And Concentration, Attention To The Worshipped One’
My internal contradictions were resolving themselves out, but still only on the plane of theory, not of practice: not for lack of good-will, but because I was still completely fettered by my sins and my attachments.
– Thomas Merton: ‘The Seven Storey Mountain’, 1948
