Devotee: Prabhupada, I heard it said that the spiritual master will always, will always come back until his devotees, his disciples, have achieved God realization. Can you explain that?
Prabhupada: Yes. But don't try to take advantage of it. (laughter) Don't try to give trouble to your spiritual master like that. Finish your business in this life. That is especially meant for those who are slack. His devotee, his disciple should be serious in serving spiritual master. If he is intelligent he should know that "Why should I act in such a way that my spiritual master has to take the trouble to reclaim me again? Let my business be finished in this life." That should be the right way of thinking. Not that, "Oh I am sure my spiritual master will come, let me do all nonsense." No. So if you have got any, I mean to say, affection for the spiritual master, then you should finish your business in this life so that he may not come again to reclaim you. Is that all right? Don't take advantage of this business. Rather, be serious to finish your business. That is a fact.
There is an instance of Bilvamaṅgala Ṭhākura. Bilvamaṅgala Ṭhākura was in his previous life, elevated to almost prema-bhakti, highest platform of devotional service. But there is always chance of falldown. So somehow or other he fell down. And next life he was born in a very rich family as it is stated in the Bhagavad-gītā: śucīnāṁ śrīmatāṁ gehe (BG 6.41). So he was born in a rich brāhmaṇa family, but he became, naturally as rich boys become attached to… woman-hunter. So it is said that his spiritual master instructed him through his prostitute. At the right moment, his spiritual master said through that prostitute, "Oh, you are so much attached with this flesh and bone. If you had been attached so much with Kṛṣṇa, how good you could have achieved." Immediately he took to that position. So that responsibility is for the spiritual master. But we should not take advantage of that. That is not very good. We should try: yasya prasādād bhagavat-prasādaḥ. We should not try to put our spiritual master in a position that he has to reclaim me from prostitute's house. But he has to do it. Because he accepts his disciple, he has got the responsibility like that.
