When we say supplications we try to load their meanings in the mind and then to establish their implications in the heart. If we do this right while paying attention to the fact that God is present and listens to our supplications, after much practice we gradually develop a reflective mechanism in our system. 

What this means is that after a while when we say a supplication or even when we hear it (e.g. Alhamdulillah - Gratitude is for God) it automatically loads its meaning to our mind and establishes its implications in our heart. 

In this way we will be able to experience strong spiritual inspirations when saying or hearing a supplication, including the verses of the Qur’an.
