[Srila Prabhupada] explained that there are different grades of devotees.The lowest grade will find a little fault and make a big thing out of it.The next grade will see the good and bad in a person but give more emphasisto the bad. And the next grade will see the good and the bad and give equalimportance to both. But the advanced devotee, although he or she sees both the good and bad in a person, gives more emphasis to the good. And the most advanced will find a little good and make a big thing out of it.
