Thus, because they are temporarily or perma­nently in a state of ecstasy, they resemble "blessed lunatics." And because they resemble them, they are not responsible. And because they are not responsi­ble, they are not punishable. On their ecstatic saint­hood persisting, they come to support the people of misguidance and innovation; they spread their ways to an extent, and inauspiciously cause some believ­ers and people of truth to enter them.

from The Twenty-Sixth Letter Tenth Matter
Principles for Bediuzzaman Said Nursi's Visitors
[It was requested by some friends that a principle concerning visitors be explained. That is the rea­son this was written.]

It should be known that those who visit me either come in respect of worldly life, and that door is closed; or they come in respect of the life of the hereafter, and in that respect there are two doors: either they come supposing my per­son to be blessed and to possess high spiritual rank, and that door is closed too. For I do not like myself and I do not like people who like me. All thanks be to Almighty God that He did not make me like myself. Or they come purely in respect of my being a herald of the All-Wise Qur'an. I willingly accept anyone who enters by this door. Such people are of three sorts: they are either friends, or brothers, or students.The characteristics of friends, and conditions of their friendship: They have to earnestly support our work and service connected with the Words and the lights of the Qur'an. They should not support injustice, innovations, or misguidance in heartfelt fashion. They should themselves try to profit from the Words.

The characteristics of brothers, and conditions of their brotherhood: Together with truly and ear­nestly working to disseminate the Words, they should perform the five obligatory prayers and not commit the seven grievous sins.

The characteristics of students, and conditions of their studentship: To feel as though the Words are their own property written by themselves, and to know their vital duty, their life's work, to be the ser­vice and dissemination of them.
