Just posting quotes here from “Surma Chashm Arya” (1886) (Collrium for the eyes of the Aryas).

…God has Vested in him a hidden faculty of receiving revelation. When human reason arrives at the limit of its reach, at that stage God Almighty, for the purpose of leading His true and faithful servants to the perfection of understanding and certainty, guides them through revelation and visions. Thus the stages which reason could not traverse are traversed by means of revelation and visions, and seekers after truth thereby arrive at full certainty. This is the Way of Allah, to guide to which Prophets have appeared in the world and without treading along which no one can arrive at true and perfect understanding; but an unfortunate dry philosopher is so much in a hurry that he desires that whatever has to be disclosed should be disclosed at the stage of reason. He does not know that reason cannot carry a burden beyond its strength, nor can it step forward further than its capacity. He does not reflect that to carry a person to his desired excellence God Almighty has Bestowed upon him not only the faculty of reason but also the faculty of receiving revelation. It is the height of misfortune to make use of only the elementary means out of those that God has, out of His Perfect Wisdom, Bestowed upon man for the purpose of recognizing God.
