A curious nature, an open mind and a willing spirit.
We live world which has the concept of "hierarchy" as one of its rules. Each level of hierarchy is build upon the previous level and "with rank, goes privilege" so to speak.
One cannot understand the next higher level using only the tools of the lower levels. Can't be done.
You are trying to use rationality, the tool the ego uses to justify its position of control over the lower levels of your physical, emotional and mental reality, to understand the levels beyond it. Can't be done.
Better to use the tools of metaphor and analogy to discover the truth about what else you are, as the greatest teacher and all under Him in the hierarchy have done.
None of which are contradictory with rationality whatsoever (with the caveat we're speaking of "spirit" as in "spirit of adventure", not the "soul").

What levels? Evidence, please?

Hm...I'll stick to biology, chemistry, and physics.
