The battle of philosophers is a battle for man’s mind. If you do not understand their theories, you are vulnerable to the worst among them. — Philosophy: Who Needs It?
I looked up a partial phrase I’ve heard somewhere along the course of my life. I did a search for ‘the language of the gods’, and came back with this as the lead item:
In Vedic religion, “speech” Vāc, i.e. the language of liturgy, now known as Vedic Sanskrit, was considered the language of the gods. Later Hindu scholarship, in particular the Mīmāṃsā school of Vedic hermeneutics, distinguished Vāc from Śábda, a distinction comparable to the Saussurian langue and parole.
Etymology Online gives a readable version of what The Sage Dictionary provided. Here is the more readable version:
liturgy (n.)
1550s, Liturgy, “the service of the Holy Eucharist,” from Middle French liturgie (16c.) or directly from Late Latin/Medieval Latin liturgia “public service, public worship,” from Greek leitourgia “a liturgy; public duty, ministration, ministry,” from leitourgos “one who performs a public ceremony or service, public servant,” from leito- “public” (from laos “people;” compare leiton “public hall,” leite “priestess;” see lay (adj.)) + -ergos “that works,” from ergon “work” (from PIE root *werg- “to do”). Meaning “collective formulas for the conduct of divine service in Christian churches” is from 1590s. Related: Liturgist; liturgics.
In ancient Greece, particularly at Athens, a form of personal service to the state which citizens possessing property to a certain amount were bound, when called upon, to perform at their own cost. These liturgies were ordinary, including the presentation of dramatic performances, musical and poetic contests, etc., the celebration of some festivals, and other public functions entailing expense upon the incumbent; or extraordinary, as the fitting out of a trireme In case of war.

From the descriptions, all of these approach the subject from the ancient Sanskrit, a good approach if the desire is to get lost among the ancient runes of the Hindu writings (where the festival of lights, Diwali, has its origins rooted as well.)
