There are seven planetry mantras in ancient arabian occult these are :-
1- ya zohal (i invoke saturn)
2- ya mareekh (i invoke mars)
3- ya shams (i invoke the sun)
4- ya atarid (i invoke mercury)
5- ya zohra (i invoke venus)
6- ya qamar (i invoke the moon)
7- ya mushtari (i invoke jupiter)
Note : the book said the operator must intone/chant these in thusands of reps to make effect but i think this is corrupted, maybe 9 or multiple of 9 per seassion is enough.
The quastion here is : am i allowed to use lhp knowledge in meditation or does it make the gods angry at me.
You have the absolute best library of mantras in the world inside the Temple of Zeus. Do not practice anything that has not been approved by clergy, because everything here has been throughly filtred so we all get the authentic and the best version of these practices.
For this reason, using practices from elsewhere is not the best idea, even if it doesn't make the Gods angry. You need to know what you are doing and practicing beforehand, because otherwise you could be doing practices that cause you harm, or blasphemy to the Gods, without you even realizing it, because there is a lot of corrupt information out there.
I am not saying it is the case with these mantras, because I can't be sure and it is irresponsible to make assumptions, but I would say that in this sense and regarding spiritual practices, you're better safe than sorry.
