This letter, written to Nûr Muhammad Tahârî, informs that Allâhu ta'âlâ is not like anything and that He cannot be comprehended mentally:
Hamd be to Allâhu ta'âlâ. Salâm upon those slaves of His whom He has chosen! Your honourable letter has arrived here. You write that your states have always been changing. Know that Allâhu ta'âlâ is not within the âlam, nor is He outside the âlam. He is not apart from the âlam, nor is He united with the âlam. Allâhu ta'âlâ exists. But He is not within or outside, united with or apart from it. Allâhu ta'âlâ must be known as such, must be searched for as such, and found as such. If one has reached such an understanding [that is, contrary to the above definition], though it may be in a small scale, it will be understood that one has got stuck in shades and appearances. Allâhu ta'âlâ must be looked for as a being never like anything and never comprehensible. One must struggle to reach that grade in an incomprehensible manner. This great blessing can be attained only through the sohbat of a murshid-i kâmil. It cannot be explained or comprehended through writings or words. Try to do your duty! Write about your states until we see each other!
