"Whereas I believe that there is also a spiritual dimension in addition to the deeds/actions."
Dear Brother, I have no issue with a spiritual dimension to our existence; it is not all 'dunya'.
But reading the whole Qur'an makes us more conscious of Allah through His teachings and helps us eliminate the man made practices that He has not ordained for us and which make us more 'worldly'.
It is reconstructing our thoughts after we have deconstructed the idols.
I could say 'each to their own', give up, but my thoughts tell me that religious rituals are there to keep us away from the true way of life Allah has ordained for us, best for us, so it is more important than this and I will keep trying to unchain the Qur'an.
