I’m not sure whether “Let me serve you with my tongue” is supposed to be dirty or not.
Likewise, I’m not sure whether this song is addressed to a lover or to God. ‘Bhakti’ means, apparently, “devotional worship directed to one supreme deity”. So I’m more inclined towards to think it’s a love song.
“Leave this grieving sand and sky far behind” is such a good turn of phrase. Also note the lyric change in the bridge (“let me hear the machines’ great gears squeal and wheelgrind” – it’s just “grind” in the album version.)
