During my successive periods of meditation there were revealed to me things impossible to recount. All that I shall say for the edification of the reader is this:
I learned from a sure source that the Sufis are the true pioneers on the path of God; that there is nothing more beautiful than their life, nor more praiseworthy than their rule of conduct, nor purer than their morality.
The intelligence of thinkers, the wisdom of philosophers, the knowledge of the most learned doctors of the law would in vain combine their efforts in order to modify or improve their doctrine and morals; it would be impossible.
With the Sufis, repose and movement, exterior or interior, are illumined with the light which proceeds from the Central Radiance of Inspiration. And what other light could shine on the face of the earth?
In a word, what can one criticize in them? To purge the heart of all that does not belong to God is the first step in their cathartic method. The drawing up of the heart by prayer is the key-stone of it, as the cry "Allahu Akbar' (God is great) is the key-stone of prayer, and the last stage is the being lost in God.
I say the last stage, with reference to what may be reached by an effort of will; but, to tell the truth, it is only the first stage in the life of contemplation, the vestibule by which the initiated enter.
