Father Tanner: Now, I'm saying, when this time comes when all physical things end, will any of the spirits fail to reunite with the Godhead?
Prabhupāda: Now, when, as soon as he likes to reunite. That is... That depends on his liking and not liking.
Father Tanner: Hm. But would you admit that...
Prabhupāda: There is no... You are talking of mechanically. But I am talking of that little independence. As soon as the living entity desires to unite with the Supreme Lord, he can become.
Father Tanner: Yes, but will it ever...
Prabhupāda: And so long he does not desire, he'll have to continue this material existence. So that depends on him.
Father Tanner: And could that go on and on forever, his not desiring?
Prabhupāda: Well, how can I say? You have got independence of desire and not to desire. That depends on you. If you never desire, then you continue, perpetually, material life. But there is chance.
