It might be better in some cases to think in terms of function rather than meaning. What is the essential function of, say, simple rituals like the Lesser Ritual of the Pentagram or pagan circle castings? Their role, as I see it, is to cause a shift in states of mind, from everyday existence to a spiritual state. Concepts of elements, mysterious deity names or complex theoretical presentations of the universe have, in the end, very little to do with the desired effect. It is the act of recital and motioning that counts.
So, instead of wasting time analysing the symbolism of the most basic rituals, why not just make up words from scratch? Don't even try to give them any kind of meaning. That way only lies doubt and second-guessing and endless analysing.
Below is an example of a ritual based on the formula of the Ritual of the Pentagram.
The Rite of Alzagor
- Thou shalt stand firm and recite the Words of Commencement: Alzagor dakos sardaron!
- Next thou shalt trace the symbol of the Pentagram before thee, on thy right hand, behind thee and on thy left hand, and as thou dost so thou shalt vibrate the Four Words of Power, one for each quarter: NERHALAG! OGNADAR! KALASTHON! YUGZURA!
- Thou shalt draw in the energies of the Flaming Pentagrams whilst reciting the Eight Syllables of the Chaotic Mantra: Targohora nehel berzag!
- Last thou shalt exclaim the Invocation of the Nameless, thrice: Yah-no! Yah-no! Yah-no!
