Salaam,
Through both reading and using our minds. We cannot really say we are Muslims if we have never read the Quran in a language we understand. Once we do read it properly, we will naturally start to think and reflect upon the verses and this is what we are prompted to do by the Quran.
And reading it regularly will InshaAllah make us see it in a different light everytime as we will ponder over the verses even more.
