Rest assured that if you practice what your teacher tells you then you will improve. If, however, you practice your version of what your teacher told you then the chances are you will not. Also, if you have a constant need to be reassured as to that progress then you are probably neither improving nor practising correctly. Look at yourself. Search for that minuscule vestige of honesty, and develop it. In this there is no help – no one else can do the work for you. Meditation is taking responsibility for who you are.
