They divided Divine philosophy into two parts: one kind is that of which the knowledge can be acquired through lectures and study in schools and colleges. The second kind of philosophy was that of the Illuminati, or followers of the inner light. The schools of this philosophy were held in silence. Meditating, and turning their faces to the Source of Light, from that central Light the mysteries of the Kingdom were reflected in the hearts of these people. All the Divine problems were solved by this power of illumination. (173:2)
This Society of Friends increased greatly in Persia, and up to the present time their societies exist. Many books and epistles were written by their leaders. When they assemble in their meeting- house they sit silently and contemplate; their leader opens with a certain proposition, and says to the assembly `You must meditate on this problem'. Then, freeing their minds from everything else, they sit and reflect, and before long the answer is revealed to them. Many abstruse divine questions are solved by this illumination.
