Like many of our disciples, as a matter of civilized man, they should have remained at home, obedient to the parents, get married and live peacefully with father and mother. Of course, these European, American boys they do not do that. But it is expected that should be like that. Just like yourself: you should have lived with your father. He also. But you did not do this. So take it for granted, out of sentiment you took to Kṛṣṇa consciousness. Tyaktvā sva-dharmam. To live family life, peaceful life, obedient life to the fathers and mother, this is called sva-dharma.
So one gives up this sva-dharma, tyaktvā sva-dharmam, and takes to Kṛṣṇa consciousness, surrenders to Kṛṣṇa, but some way or other—by association, by māyā's trick—again he falls down, just like many of our students have gone . . . not many, a few. So Bhāgavatam says, yatra kva vābhadram abhūd amuṣya kim that, "What is the wrong there?" Even if he has fallen down half way, still there is no wrong. He has gained something. That much service which he has already given to Kṛṣṇa, that is recorded. That is recorded. That is to his credit: "So this living entity has given service." But other man, he's very honestly living as a good citizen, as a good family member and good brāhmiṇ, good kṣatriya . . . so ko vārtha āpto 'bhajatāṁ sva-dharmataḥ. He's sticking to his own principle of life, but he's not a Kṛṣṇa conscious devotee, then what is his gain? He'll simply take the fruits of his material activities and he'll have to accept another body according to that.
But here, as it is assured in Bhagavad-gītā, that śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo sanyate (BG 6.41): this man, who took by sentiment Kṛṣṇa consciousness but could not follow it to the end—by some way or other, he has fallen—but he'll be given chance to take birth as a human being, guaranteed, in rich family or in nice devotee family, yogī family or brāhmiṇ family.
