Salam. I've seen in Noor-Ul-Huda Qalan that Hazrat Sultan Bahu [ra] speaks of the superiority of Kalima Tayyiba. What is the correct way to recite this? If this "correct way" is a way that I can reach after I've reached a certain spiritual level, then can I just recite Kalima Tayyiba normally? Salam. Jazak Allah Khairan.
