Sufis, the investigators on the inner path directed toward the true meaning of self-cognition, have invited mankind to return to this point of reference, the inner heart, and to understand it as the proper laboratory for achieving a more advanced human understanding. Let us further investigate this point of view and taking the eye as our example see how the thinking of Sufis differs from the thinking of both philosophers and scientists. The eye is equipment for seeing, a tool given to a human being by nature. Man has also received the power and energy of sight to make use of this organ. But this power of receiving works in harmony with all the other energies of nature.
Nature also sees and thus possesses the power of sight.
Nature is also intelligent and possesses the power of logic. If it did not, neither would you have these powers and faculties, since you yourself are a part of nature, so that whatever faculties you have you owe to nature's providence. In every case, our faculties are bound by nature to their particular purposes. Even if it perceives only that which is within its purview, certainly it sees within a much higher and broader boundary than our own. Yet we cannot deny that nature can see, because nature cannot provide to individual beings qualities that it does not possess itself.
