God has never told us that we can find within ourselves what is the soul and what is the spirit.
Such an approach is wrong and the person trying to do it is also wrong.
God has never meant for us to do this, because looking within will only result in darkness.
Self-examination in this regard will never result in our finding the Light.
For all is dark inside us.
To follow this track will lead us nowhere.
It is a blind alley.
So we must stop doing it.
