Being accomplished in your practice doesn't mean that you have amassed a great following. It isn't your ability to know every answer, to be the provider of every solution. It doesn't matter if your students think you can walk on water or you have amazing abilities.
Your practice has borne fruit if you are less concerned about what others think of you.
Your practice has hit its mark if you don't fear being insignificant.
Not chasing after praise or worried about being blamed are signs of success.
You've made great progress when you are no longer scheming for gain or using any measure at all to protect against loss.
If you no longer feel overwhelmed by suffering, your practice is ripening.
If you no longer find yourself wishing for happiness, it is a strong sign of accomplishment.
