Actually one who is nārāyaṇa-para, pure Kṛṣṇa conscious devotee of the Lord, he's not afraid of going to hell or being promoted to heaven. For him everything is all right.
- nārāyaṇa-parāḥ sarve
- na kutaścana bibhyati
- svargāpavarga-narakeṣv
- api tulyārtha-darśinaḥ
- (SB 6.17.28)
For heaven or hell, it doesn't matter. That is pure devotion. Anyābhilāṣitā-śūnyam (Brs. 1.1.11), without any desire. That is also desire that, "I am going back to home, back to Godhead." But that desire is very highly qualified desire. But a pure devotee does not desire even that. Anyābhilāṣitā-śūnyam (CC Madhya 19.167).
They do not desire . . . what to . . . they do not desire even to go back to Godhead, and what to desire for being elevated or promoted to the heavenly planet. They simply want, "Let me remain wherever Kṛṣṇa desires. I may be engaged in His service." That is pure devotee. That's all.
Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (CC Madhya 19.167). Jñānī, they want to merge. Karmī, they want to be elevated to the heavenly planet. Yogī, they wants mystic power. They want something. A pure devotee does not want anything. Therefore it is called ahaitukī. Hetu means cause. "I am serving God for this cause: I'll go back to home, back to Godhead." That is also cause. So ahaitukī. No cause. "Kṛṣṇa is my lovable Deity. I must serve." That is pure devotion.
