as salam alaikum
our relationship with Allah should be based on worship and servitude. Concentration may be a part of worship but it is not its finality because to focus on ideas and meanings, as lofty as they may be, can be in some cases a form of distraction from the One to Whom our worship is directed. There is a fundamental element in worship distinguished from different forms of exercises and concentration. Mere concentration may improve our capability of meditation on an object but may not be classified as real worship. That is why sometimes worship has been compared to a lover admiring his loved one without focusing on what he is saying to him.
If our intention is to satisfy Allah, we won't have any ambition to reach a particular state or stage and that is when the heart get ready to receive more favors and grace from his Lord. In other words, a pure intention, attitude and lifestyle in the light of the teachings of Islam are often more effective than alienating yourself trying to grasp something behind single moments through basic concentration.
With prayers for your success.
