God willing, this Thirty-Third Letter of Thirty-Three Windows will bring to belief those without belief, strengthen the belief of those whose belief is weak, make certain the belief of those whose belief is strong but imitative, give greater breadth to the belief of those whose belief is certain, lead to progress in knowledge of God –the basis and means of all true perfection– for those whose belief has breadth, and open up more brilliant vistas for them. You cannot say, therefore, that “One window is enough for me,” because if your reason is satisfied, your heart wants its share as well, and so will your spirit want its share. Your imagination will also want its share of the light. The other Windows are also necessary, therefore, for each contains different benefits.

In the Treatise on the Ascension of the Prophet Muhammad (PBUH), it was primarily the believer who was addressed, while the atheist was in the position of listener. But in this treatise, it is the denier who is addressed, while it is the believer who is in the position of listener. This should be taken into consideration when looking at it.

Unfortunately, due to an important reason, this letter was written with extreme speed. It has also remained in the state of the first draft. There will certainly therefore be some irregularities and defects in the way it is expressed, which are due to me. I request of my brothers then that they look at it with tolerance, and correct it if they are able, and pray for my forgiveness.

Peace be on those who follow Guidance, and may those who follow their own desires be censured.

Glory be unto You! We have no knowledge save that which You have taught us; indeed You are All-Knowing, All-Wise.1

O God, grant blessings and peace to the one whom You sent as a Mercy to All the Worlds, and to his Family and Companions, and grant them peace. Amen.
