"… If you have not experienced any obstacle in your enterprises, it is
because your heart is pure, that your soul is without stain, and that virtue, probity, and honour will always be dear to you. A man who had the least reproach to make to himself, who had destroyed the good of others, or who had only the intention of so doing, would not be able to participate in our mysteries. In vain would he have in his possession all that you see, our magical language known to him.
The celestial powers—aerial, infernal, terrestrial, and those of the oceans and fire—would rebel against him. All that he wished to undertake would turn to his shame and his confusion, and at each invocation which he might make, the powers that he implored for help and intervention would answer him:
Renounce thy projects. Thou art guilty. Before commanding us, purify thyself, expiate thy faults."
Has anyone ever ascertained with certainty the exact nature of this reproach, and which undertakings are deemed reproachable and unworthy?
Note that the old man in the story allowed him to kidnap a Sultana at the expense of a massacre of servants who were beheaded.
