That is how Krishna deals with His devotees. By His mystical ways, He creates a situation for us by which we will hanker more for His presence, and by chanting His names, we will feel an increase of that presence. It will be so satisfying that we won't want to stop. It may seem that such a state of conciousness is too far away to imagine, but it is not far at all. The seed has been planted and it will grow. As with any seed, the more sunlight and nourishment it gets, the faster the growth.
