Actually you are not trying to understand. No one said Sufism is wrong. The main thing is, everything should be inside the boundaries of Shariat. For taking any hadith as authentic, we have to refer to it's chain. If there is not a chain of a hadith then it cannot be accepted as true. This is not a chain of narrators that Jibreel alaihi assalam taught Rasool Allah then he taught Hazrat Ali The chain of Hadith is something like this: This is the first hadith of Sahih Bukhari: حدثنا الحميدي عبد الله بن الزبير قال حدثنا سفيان قال حدثنا يحيى بن سعيد الأنصاري قال أخبرني محمد بن إبراهيم التيمي أنه سمع علقمة بن وقاص الليثي يقول سمعت عمر بن الخطاب رضي الله عنه على المنبر قال سمعت رسول الله صلى الله عليه وسلم يقول إنما الأعمال بالنيات وإنما لكل امرئ ما نوى فمن كانت هجرته إلى دنيا يصيبها أو إلى امرأة ينكحها فهجرته إلى ما هاجر إليه The bold is the chain. Then we have muhadditheen who tell us whether the narrators are strong of weak. They grade the hadith. This is how we take ahadith and narrations. We don't just pick up a book and say, o look... It's written that Jibreel brought this dua. What is the chain? I brought black magic, because you said you have experienced so much through this dua. So my question is that if experiencing supernatural things is the criteria of being right then you will experience more super natural things in doing black magic and if you go to Hindu Yogis, you'll see much more than this.
