It is stated in the sutras that practitioners have three levels of classification. Top-level practitioners are able to make progress everyday. Those in the middle fare a little worse but are still capable of some breakthrough each month. Even the ones in the low level can better themselves at least by the year.
Let us ask ourselves: “Which level do I belong? Did I or can I improve over last year?” If the answer is no, then we do not belong to any one of the three levels of practitioners. Since there is no fourth level, it just goes to show that we are practitioners in name only. And even that could be an overstatement.
