What does it mean if knowing yourself is akin to knowing LUE

What does it mean if knowing yourself is akin to knowing LUE? [life the universe and everything].

I can’t make head nor tail of this, and I couldn’t begin to explain in detail… but as I contemplate the nature of reality or of myself, I end up thinking that the answer if there is one, is the same for both those things. Whereas I wouldn’t consider the meaning of a brick to also be the meaning of LUE, it has limits to its descriptiveness where we don’t even though we probably should.

For example; if I ask ‘is existence [the universe] subjective or objective’, I can then ask am I an subjective or objective entity. Then I come to the conclusion that both are subjective and nothing is thence objective. More, that I am the same as existence, we both contain the same fundamental nature as subjective entities [and subjective to what?].
