(Prabhupada's lecture - Śrīmad-Bhāgavatam 1.16.8 - Los Angeles, January 5, 1974)
So once one becomes situated in hari-līlāmṛtaṁ vacaḥ, that means he has stopped his process of death. So this dying again of this body... Of course, this body is material. It must make a show that this material body... But he is a spiritual body. He is going back to home, back to Godhead. There is no doubt about it. Therefore Yamarāja's duty... Yamarāja is Vaiṣṇava. He wants to see that you do not die again. He wants to see that you continue your deathlessness. Now you are engaged in kṛṣṇa-kathāmṛtaṁ vacaḥ. So that is the point of... Just like a diseased man. A diseased man, as soon as goes to the physician and he gives the right medicine, and he takes it, that means his diseaselessness condition has already begun. It will take little time.
So in the meantime, in that treatment time, diseaselessness condition, if you make another infection, that is your fault. Otherwise, deathlessness begins from the day of initiation. Ādau gurvāśrayam. As soon as you take shelter of a bona fide spiritual master, your point of deathlessness begins immediately. Immediately. And if you continue the advice and instruction of the spiritual master, or the śāstra, then you become deathless. No more death. And Yamarāja wants to see that actually you are continuing your deathlessness process. This is... Kṛṣṇa consciousness is so nice. Therefore it is advised.
