As Mr. Kuşçuoğlu narrates, this meeting occurred after a period of yearning and waiting for his unknown spiritual guide (Murshid).
Subsequently, I especially prayed Allah to make me meet my spiritual guide.In 1949 he had swore an oath of allegiance to the Qadiri and Rifai Shaikh Haji Mustafa Yardımedici, the caliph of Sayyid Shaikh Ali Sezai Kurtaran who is also known as "the Conqueror of Maraş".
He wrote the following books: “The Brotherhood We Need”, “Tasawwuf and the Dhikr of Allah”, “Metaphysics 1”, “Metaphysics 2”, “The Mercy Drops of Modern Age: From the Divine Compassion to the Divine Wisdom”, “Tasattur, Hijab and Adab in the Quran”, “The Handbook of Makarimul Akhlaaq (The Honorable Morals) and Al-Tariq al Mustaqim (The Straight Path) for Galibi Dervishes in Charge, and Islamic Tasawwuf Principles”, “The Hadj Guide” and “Erudite Remarks and Experiences Compiled from Ahl al Hal”.
