The first thing you should not let wane is devotion to your spiritual friend [kalyanamitra]. Your mental attitude of admiration, dedication, and gratefulness toward the spiritual friend should not diminish. The second thing you should not let wane is a delightful attitude toward lojong, or the taming of the mind. Your appreciation for receiving such teachings as lojong or mind training should not diminish. And the third thing you should not let wane is your conduct - the hinayana and Mahayana vows you have taken.
