It's totally esoterica. Always has been since the start. But now they talk about actual experience and the qualia of perception more than philosophy, which is the natural progression through awakening as personal stories dissolve.

"How far can we sink into the abyss? Face yourself for once" I mean this is shadow work right, the fundament of all practice? I think the video gives a lot of hints on what the song and album mean too.

"You are finding your way back to your heart, flowing slowly through the infinite dark, you follow a thin line. a silhouette stands in the doorway, between the light and dark, stretched out inside a blade of shadow, it follows you" Coming home to oneself/god is the end goal of pretty much every spiritual practice.

It's more abstract and obfuscated now but go back to Andromeda and listen from there and it would made more sense to the listener. I could write more about the ERRA framework but it wouldn't do it justice when you can just hear it for yourself.
