What we imagine and how we imagine it are images for the observer.. an observation.. Spirituality is indeed how we deal with observations.. Those observations are spiritually discerned..
Quite a test it is being a human.. a spiritual test..
Are you DNA and a DNA'osaur, or spiritual?..
Most of Jesus' parables ask this question..
And Darwin and Dawkins puts it another way, same question..
Your post reminds me of the recent article by Lanza, a noted biologist, who wonders whether reality is actually the result of observation, i.e. that it doesn't exist before it is observed. His musings are a lot like those who believe a tree falling in the forest doesn't make a sound unless someone is around to hear it.
For me, reality is God's will and unknowable in its fullness.
