Lyric discussion by djmongo 

To me this song is epic on the grandest scale. The song begins on the beach amidst the waves of the sea, but also amidst the waves of sunlight. The pinging of the opening notes suggests both the submarine sonar and the echoes of the big bang. This is about creation and evolution, wave-particle duality, and the call of evolving DNA to itself in a grand love song which echoes throughout all time, so that in each life, each reincarnation, we are calling to ourselves, and our soulmates, our fathers, mothers, sisters, brothers, lovers, sons and daughters, our friends and even our enemies, as we have been all of these to each other throughout our countless incarnations, and in this endless cycle of rebirth and evolution, we are the Universe becoming conscious of itself, so that each morning when the sunlight hits our eyes, and we are conscious of it, of that echo of creation, we are the evolution from that time, calling back to our past and present self.

I should say the lyrics involve not just waves of light and waves of water, but also waves of sound, of course.

I'm not sure if you nailed exactly the interpretation but I loved it. Great way to see it and the way I see it agrees in most of what you've just said.

After saturating in this song for a bit, I agree most with this interpretation. However, the structure of the poem suggests at the above even further. Run-on sentences make up a good half of the song. Much like life, lineage, and history altogether: we are but a long string of biochemical reactions made into sentient beings that leave their individal mark on the great cognitive consciousness known as history and knowledge, be it big or small. The lyrics are written in one big run-on sentence, strung along just like us. Each sentence wanders about, again, just like us.
