There are very few mashaikh who I would describe who are fana fil rasul. With regards to shaykh Nuh and Shaykh Yaqoubi could you elaborate. Also could you tell me which naqshbandis and qadris talk about esoteric concepts? What do you mean esoteric? Could you give some examples? I came across some people who were giving out titles like fana fir rasul like candy. Their shaykh said infront of me that maulana yusuf khandalwi was fana fir rasul about which I had zerp% doubt. But then when some of his followers were claiming the maqam I was imagining their life with the life of maulana yusuf rh. There was no comparison. The true objective is shariat and sunnah. Nothing can compare to that.
