So I’m guessing munka, visuddi, suryae, satanama, agni, vreem, etc., etc. can all be used to protect. But what ‘type’ of protection do they have specifically? And what other non-protective uses do they have? And what is their correct .mp3 vibration? (I suggest a new JoS webpage dedicated to sanskrit mantras).
Not really. Visuddhi is water elemental cleaning mantra, Satanama is balancing, anti-aging and alike mantra, Agni is pure elemental fire...
Sanskrit is a whole language, it has almost infinite but definitely thousands of thousands of defined mantra. Same with ancient Greek, Latin, and other ancient languages.
General Yeager have shared a book full of Sanskrit mantras but I advise you to use the ones you know well, that all of us uses and is mentioned on the JoS or a lot on the forums.
Because these definitely work the way as intended, as we have experience with them.
If you want protection, you have Algiz, sowilo, Tiwaz, Thurisaz which completely does the Job and you can do multiple types of AoP with these.
If you want to heal you can use a sun mantra or Wunjo.
If you want to clean yourself you have sun mantras (Surya, Aum Suryae [The "EA" at the end is only there when there is AUM in front of!], sowilo, Raum, ..) or Visuddhi, or (Helios, or Agni but these are more dangerous mantras)...
In fact the runes itself can satisfy all your spiritual needs and we wouldn't even need to use sanskrit or any other mantras. Germanic people used only Runes for their spiritual works. Vedic people only used Sanskrit mantras for their spiritual work.
We actually have too much to choose from, the Runes are perfect because there are not overwhelmengly a lot of them, and can satify any need.
