Even one is finished, this material body . . . sometimes they commit suicide out of frustration, that "This desire is not fulfilled. Let me commit suicide." No. That is ignorance. Desires continue in the subtle body—mind, intelligence and ego. And to fulfill the desire, Kṛṣṇa will give you another body. If we make a desire, it must be fulfilled, and Kṛṣṇa will give you facilities. Bhrāmayan sarva-bhūtāni yantrārūḍhāni māyayā (BG 18.61). Desire is so strong. So how to make it zero? That is not possible. To make it zero means no more material desire. That is to make zero material desires. Sarvopādhi-vinirmuktam (CC Madhya 19.170).
That is more lucidly explained in the Nārada-bhakti-sūtra. Desire means we should give up the desire of this body of designation: "I am Indian; you are American," "I am Hindu; you are Christian." These are all designation of the body. I . . . accidentally I am born in India; therefore I call myself Indian. You are accidentally . . . not accidentally; some way or other born in . . . you are American. Accidentally somebody takes birth in the Hindu family; he becomes Hindu. Accidentally he takes birth in the Christian family; he becomes Christian. These are all designation. So when we give up this designation, that is desirelessness. Designation. Everyone is acting, they are fighting, they are making so many plans. Why? "We are Indian" or "We are American," "We are Russian, and the Russian must exceed the Americans," "Americans must exceed . . ." This is going on, on the platform of designation. When we change the platform and we simply desire how to serve Kṛṣṇa, that is desirelessness. Otherwise not that desirelessness means I become zero. That is not possible. Because I am a living being, I am living soul; how can I be desire . . . (break) . . . loke panthāḥ kṣemo 'kuto-bhayam (SB 6.1.17). If you want to be designationless, then come to the association of such persons who are suśīlāḥ sādhava yatra nārāyaṇa-parāyaṇāḥ (SB 6.1.17), persons who are simply interested in serving Nārāyaṇa. Nārāyaṇa parāyaṇa means . . . parāyaṇa means they're always ready to abide by the orders of Nārāyaṇa. Nārāyaṇa . . . those who have taken the path of Nārāyaṇa, devotional service, as their life and soul, they are called nārāyaṇa-parāyaṇāḥ.
