Other than the ritual dagger is there anything that I should have for the ritual?
Does it matter whether or not I have the candles on my altar lit up?
The LBRP is a fairly minimalist ritual. The dagger is fine (you can even get away without it).
The only real “physical” concern with doing the LBRP is whether you have adequate empty space around you to do it in, mostly for focus purposes i.e. not worrying about bumping into anything, having your mind telling you “no space for the angel” etc.
I conjured the archangels once in LBRP and i felt the difference.I didn’t said before me Raphael,behind me Gabriel etc.
I invoked them in my own way,repeating the conjuration until they were really there.The effect was very powerful and stabilizing.
