Immortality lives in paradise
whereas you can be mortal in Eden
therefore the tree of knowledge
which allows you to observe your nudity
functions as an exchange of knowledge
for mortality.
There is no prohibition
but a warning regarding the endangerment
you are facing.
However, that is not the problem.
It is the deception due to misinformation
which is not necessarily an act of deceit
because life outside paradise
is unknown.
Therefore the deceived ignorance
does not merely get transformed
into mortal knowledge.
Because it lives after the trial
which becomes a crucible.
It is no longer merely a life gained awareness
but an experience as well
since it is wrong
that it is interpreted
as a sin.
