The universe is an imaginary concept, and my physical experience of now is the true size of my existence.
Being 100% truthfull to myself, my mind is the only mind that does exist, as everything happens in my mind, and I'm the only person that can feel. If I disagree with such an interpretation, then I'm lying to myself.
The only place I can be is here now.
Needing to prove something to someone else is a mode of being separated, and I am one.
