So now, somebody may say that "If a devotee is engaged in the service of the Lord, that's all right, but if his behavior is not up to the standard, then what happens to him?" Of course, a devotee is naturally developed, developing the twenty-six good qualities, but even if he does not develop those qualities... Of course, that very quality, that he is a devotee of Kṛṣṇa, that is sufficient. But still, if somebody is not up to the point, but he is unflinching, not moving, he is perfect devotee of Kṛṣṇa, then Lord Kṛṣṇa says, api cet su-durācāraḥ. Api cet su-durācāraḥ. Durācāraḥ means his conduct is not good, and su-durācāraḥ means still further. So api cet su-durācāro bhajate mām ananya-bhāk. Ananya-bhāk means "Without deviating his attention to any other demigod or any other business, if one is simply cent percent engaged in My service, but his character is, general activities are not so to the point, still," the Lord says, sādhur eva sa mantavyaḥ (BG 9.30). Sādhu means a pious man or a religious man. Sādhu means the honest man and all good qualities. Still, although he is found that he is not to the standard, but his only qualification is that he is acting in Kṛṣṇa consciousness sincerely... It may be...
Suppose I have got some bad character from the beginning of my life, but I have understood that "Kṛṣṇa consciousness is very nice. I shall take to it." So I am trying, trying my best. But at the same time, because I am habituated to something, I cannot give it up. Although I know that this, my habit, is not good, but still, habit is the second nature. I cannot give it up. So Lord Kṛṣṇa recommends that "Still, he is good. There is no question that he is not a sādhu or he is not an honest, he is not religious man. That simple one qualification, that he is Kṛṣṇa conscious, and he is acting sincerely, but failing sometime, but still, he is to be taken as sādhu."
