Elijah

I don't think this song is necessarily about any specific ritual, it apparently has a intense Hindu/Indian theme to it like a lot of other songs (Prana Ferox, Palmcorder Yajna, Raja Vocative).

Coconut oils, cast iron kettle (A Kalasha vessel), incense, and the fire.

In plenty of Hindu rituals and festivals, coconuts and their oils are used in connection with Kalashas; of course incense plays a role (c'mon, they sell it in every freakin' Indian gas station); and idols are everywhere too...

The thing I find interesting is the line "let the fire take it's toll/I'm coming home"- I kinda feel that it goes along with the "set the table/those three extra places, One for me, one for your doubts, and one for God" because with fire "taking it's toll" It sort-of goes along with the theme of sacrifice...incidentally sacrifice is essential during a Yajna.

Now looking into that, it could open up a ton of possibilities in relating to the Alpha Couple.
