Not vague at all, as stated earlier, a general comment. Not directed at you or any particular member. Now do you understand? Trash? No.
If I may, I read your quote, and I had to think this over, but the Universe is everything, which of course would include imagination. Then I wondered how could my imagination possibly be bigger than the universe, when I'm unaware of 95% of the Universe, limited to .03% of the electromagnetic spectrum, that persuades me that, in trying to imagine something bigger than the Universe is - what is it called - circular logic? For example, my imagination is limited to some amount of "creative speculation" (my term) by my brain capacity, my knowledge, health, memory, DNA, etc. There is a limit to what can be imagined. That limitation, inside of me, is quite tiny; powerful, magnificent, but bigger than all that is? That's quite a stretch, for me. Your quote was provocative for me, and I thank you for the opportunity to give my brain a shake.
