Thank you for your good question!
We need to be like children. How a child learns something so easily? Because that child is not concerned about “erasing” what he has learned. He is not concerned in analyzing stuff and comparing to find “faulty” information, to contrast and to weigh ‘pros and cons.’
A child is open to “learn,” accepts without comparison. If that which he has learned brings some benefit, a child will stick to it until something else comes up. Probably that is the reason why BapDada calls us children most of the time; even though we like to play “children” around Baba, our minds do not.
It is excellent that you realize those “clouds” coming into your mind. Realization has its own “cure.” After that, there is no need to “do” anything else.
