(47) Divine wisdom is true science.

You should not dare to speak of God to an impure soul.

The wise man follows God, and God follows the soul of the wise man.

(15) Notwithstanding this clear pronouncement of the Koran there are those who, through their ignorance of God, do transgress these limits, and this ignorance may be due to several different causes: Firstly, there are some who, failing to find God by observation, conclude that there is no God and that this world of wonders made itself, or existed from everlasting. They are like a man who, seeing a beautifully written letter, should suppose that it had written itself without a writer, or had always existed. People in this state of mind are so far gone in error that it is of little use to argue with them. Such are some of the physicists and astronomers to whom we referred above.

(1) Know, O beloved, that man was not created in jest or at random, but marvelously made and for some great end. Although he is not from everlasting, yet he lives for ever; and though his body is mean and earthly, yet his spirit is lofty and divine. When in the crucible of abstinence he is purged from carnal passions he attains to the highest, and in place of being a slave to lust and anger becomes endued with angelic qualities. Attaining that state, he finds his heaven in the contemplation of Eternal Beauty, and no longer in fleshly delights. The spiritual alchemy which operates this change in him, like that which transmutes base metals into gold, is not easily discovered, nor to be found in the house of every old woman. It is to explain that alchemy and its methods of operation that the author has undertaken this work, which he has entitled, The Alchemy of Happiness. Now the treasuries of God, in which this alchemy is to be sought, are the hearts of the prophets, and he who seeks it elsewhere will be disappointed and bankrupt on the day of judgment when he hears the word, "We have lifted the veil from off thee, and thy sight to-day is keen."
