This page contains spoilers about the Heartbound ARG. If you want to solve the puzzle yourself, avoid reading this article.
There are two non-puzzle content streams in Phase 1, first the Guardian Glyphs and second the text HTML comments. It's not clear who is making the statements. There's a suggestion in the comments that attempting to do both the light path and the dark path won't work.
Guardian Glyphs Translation
This body is an illusion
This mind is a collective
We are closer to the source now
Memory is the key to this mind
This world is our undoing
This world is our beginning
