It's simple. If a belief is formed by repetition then to uncover beliefs can also by repeating something that will be positioned as a new belief. If in the world of self-development we know the term affirmation, the positive words are repeated in a certain time.
For example these words, "I am every day more confident". The goal is to put the words into a program of beliefs. But this repetition method only wastes time if your subconscious gate is still closed tightly. Finally the repetition will be rejected.
But I observe the way this repetition will actually cause the effects of alpha state which we will discuss in point 5. If you wirid / dhikr for example. Long after a little sleepy? Now that means the subconscious gate is open and the repeated words will come in. Hence the order of the ritual of prayer is dhikr repeatedly first and it makes somewhat sleepy a little (alpha state) and then the next stage we pray. Is not it? So when we pray, our minds are not critical and sabotage our own prayers. So if our prayer is not working, it could be the wrong one is not his prayer but we lack a lot of his dhikr. So when prayer, our critical logic is still kafir aka aka kakehan alias most thoughts.
