It is because you are unable to distill your darkness through conscious sanity for the sake of your own fleeting innocence, lest you do and be forever lost, swallowed whole by your evil. The words mean nothing if you cannot comprehend there meaning. So even at its description ones mind falls useless to imagine it. Incomprehensible doesn't even begin to describe the poultry insufficiency of all earthly terms. It does not want to be understood by Man for it does not need it. It just is and all just accepts. Hail Him, Son Of He The one who Balances Everything.
