Layers and realms of the universe and heavens,
levels of spiritual mastery or achievement,
exist only as pointers to that which is in you.
The truth is never really 'out-there',
to be reached for, or so on.
All of that, and the truth itself,
exist by one root.
All such ideas
are mere pointing to ways of uncovering the mystery
who's clearest answer is in your own being.
