Looks like a subtle, or subliminal even, tome for Earth Day.
Avant "Garden" - Malstrom (storm)
Mer de Noms (Sea of Words) - A perfect Circle (our globe or cycle of life)
Flor de Loto (Lotus Flower) - Madre Tierra (Mother Earth)
I'm surprised you didn't see the clues right in front of you.
And, of course, there's nothing more Earth Friendly than Return to Forever.
