I agree! Put the Quranic sails at our backs so that it drives mankind forward.
I disagree. The physical ritual is nowhere mandated in the Quran as you suggest or we would have an equivalent 'ablution' verse to show us what we need to do. Something this important must not be left to multiple verses that are open to interpretation over timings, words and acts to be performed.
The physical act has become the most important aspect of salat and I reject this. Reciting words you cannot understand back to Allah during a 'salat' is mindless.
