If you go by the idea of the Rambam that learning Physics and Metaphysics fulfills the commandment to love and fear God it makes sense to start the day with those two things right when one gets up.

If you go by the idea of the Rambam that learning Physics and Metaphysics fulfills the commandment to love and fear God it makes sense to start the day with those two things right when one gets up. [The main thing to understand is that you do not need to understand,.. Say the words and go on in order. as the sages said in the Gemara Shabat.]

The thing is that both have to be directed and intended towards the worship of God.

I am referring here to the parable the Rambam writes in the Guide about the state of the king. There was a state with people outside the state, others in the state, others in the capital city and still other close to king in his palace. These to the Rambam are barbarians, people with natural law morals, people that learn the Oral and Written Law, and still others closer to God --physicists and philosopher and prophets. But all need to be facing the King.

["Metaphysics" refers in the Rambam to that of Ancient Athens. But the hint is clear that he means specifically the Metaphysics of Aristotle. Though not called by that name by Aristotle himself, still by the time of the Rambam, that was well known as the name of that set of books.]
