That is more lucidly explained in the Nārada-bhakti-sūtra. Desire means we should give up the desire of this bodily 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) ...want to be designationless, then come to the association of such persons who are suśīlāḥ sādhava yatra nārāyaṇa-parāyaṇāḥ, 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.
So what is the qualification of nārāyaṇa-parāyaṇa? It does not require any qualification to become nārāyaṇa-parāyaṇa, but if you become voluntarily nārāyaṇa-parāyaṇa... Nārāyaṇa-parāyaṇa means my life is now dedicated for Nārāyaṇa. Nārāyaṇa, Kṛṣṇa, Viṣṇu, they're the same. So that is qualification, if you simply take it as vow that "From this day my life is dedicated to Nārāyaṇa, Kṛṣṇa." Sarvopādhi vinirmuktaṁ tat paratvena nirmalam (CC Madhya 19.170). As soon as we take this vow, that "From this day my life is dedicated to Kṛṣṇa. Kṛṣṇa wants everyone to surrender. I surrender unto the...," from that day you become free from all designation. Simply this determination, that "From this day I belong to Nārāyaṇa, or Kṛṣṇa. Whatever He wants..." That is the teachings of Bhagavad-gītā So long Arjuna... That is a superficial picture. Arjuna is always for Kṛṣṇa, but just to teach us, he became for his family. He became... In the warfield, when there was to be fighting, he became to the family side and he said, "My dear Kṛṣṇa, how can I fight with my family? They are my brothers, they are my nephews, they are my grandfather, they are my teacher, the other..." Because it was a family fight, five brothers and hundred brothers. So at the warfield he became perplexed, that "I am fighting with my family. The fight means to fight with enemies. How is that? What kind of war it is? Eh? I have to fight with family." He said, Kṛṣṇa, "So who has taught this kind of fighting, Kṛṣṇa, to kill his own brother, his nephews and...?" Therefore that means he leaned to the family side. This is designation. This is designation. Because he belonged to the Kuru's family he took side of the family. But after hearing Bhagavad-gītā, after understanding Kṛṣṇa, when he came to the conclusion that "I must be with Kṛṣṇa's side, not to the family side," then he became perfect. After hearing thoroughly Bhagavad-gītā, he... Kṛṣṇa said, "Now what you will do? To the family side or My side?" Yathecchasi. That freedom is there. Yathecchasi: "Whatever you like, you can do. I have given my instruction."
