"This advice is for this whole universe. It comes from the heart of Mawlana Shaykh Muhammad Nazim al-Haqqani, from the heart of Mahdi (as) and from the heart of the Prophet (s). These jewels are not thrown into the hands of the ignorant. You can never find these things in books. All the oceans of knowledge that had been forbidden to previous saints and hidden within the hearts of later saints will be opened."

~~Mawlana Shaykh Muhammad Hisham Kabbani 

106 Suhbas by the Muhammadan Inheritor of our time, the Nurturer of the Knowers of Allah, Sultan al-Awliya, Mawlana Shaykh Muhammad Nazim al-Haqqani--may Allah sanctify his secret--on the importance of the spiritual life, the infiniteness of spiritual knowledge, the supremacy of divine mercy, the divine honoring of all human beings since before time, the primordiality of belief in all human beings, the defeat of one's ego as the precondition of spiritual caliphate and more.
