Ruhani Ilm is the Quran, many people have changed Ruhani Ilm and made it Quran Ayats with names of Jinn this is not Ruhani ilm because now you are changing the Quran around and adding names of jinn
there is 2 kind of healers
1. who use Talisman/Taweez/, Hijab, easy Talisman/Taweez/Hijab with odd words and symbols that they have no idea what it means.
2. Then there is a healer who spends years and years just how to learn to make one Talisman/Taweez/Hijab and that Talisman/Taweez/Hijab is made with pure Quan Surah and or Ayat no odd names, no symbols no magical squares just Surah this is the method that my teacher uses alhamdulillah.
the second way is hard to learn and long so many many people don’t learn this, this method is real Rohani Ilm the original Rohani Ilm but Rohani ilm of today Taweez/Talisman/Hijab has been changed to odd names.
When you see a Taweez/Talisman/Hijab where there are names you don’t know what it means, where there are Ayats of Quran written in the wrong order, or mixed with other Āyah it is wrong if you see Talisman/Talisman/Hijab which has one Āyah in one area, then in another corner other Āyah this is also not right and some times it takes knowledge to know what is real and what is not in Roohani ilm.
