Berhatiya is interesting. You have the conjuration oath and the names. The grand ritual with oath, spamming it 11 22 33.... to some absurd number of times a day. Names which need to be spammed to get them "unlocked".
These techniques can be very overwhelming, they involve a lot of processing. These names kind of need to be read a lot more than the numbers given, for better effects. About like the 99 names of Allah which require a lot of work. Unless you have done a lot of processing like this before, you probably should be cautious. Reciting a lot of different stuff can give annoying instability, depends on the practitioner.
In the Maarif book, I think it was suggested in there, I can't read Arabic so I am not sure 100%. The ritual with special dua kursi, not the verse but the long extended version. This one is quite good. It needs to be read a lot as well for the connection and effects.
The methods like this might not give you a live communication, many people only get dreams where they show up, crystal clear dreams where somebody comes and communicates and when you wake up you remember everything. Also states where you are somewhere between being asleep & awake and having a communication.
With the dua kursi and similar, the energy can be felt all around and sometimes it could smell like roses or some other flowers, it comes out of nowhere. This happened to me with the last 2 verses of the 9th chapter as well.
I remember a couple of people reporting getting strong powerful dreams where somebody showed up, I also had such, they came and spoke. You might also see some flashing lights or something.
Again, not sure was it in the Maarif or not but a ritual with the chapter 112 from the Quran, 1000x something a day, often they show up in dream like state.
