In one way you stop your impious activities; in other way you improve your spiritual understanding in this way. Yeṣām anta-gataṁ pāpaṁ janānāṁ puṇya. Anta-gataṁ pāpam means you stop. Anta-gatam. So if you engage yourself in pious activities, in Kṛṣṇa consciousness activities, where is the scope of dong nonsense work? Therefore it is stopped. Automatically it is stopped.
So yeṣām anta-gataṁ pāpaṁ janānāṁ puṇya-karmaṇām, in this way, te dvandva-moha-nirmuktā (BG 7.28). They have no other engagement. They do not know anything else except Kṛṣṇa. Dvandva-moha—dvandva means duality—and illusion. Moha means illusion. Nirmuktā: "He becomes liberated from these two things." Duality means "Whether I shall become Kṛṣṇa conscious or this conscious, material conscious or this . . .?" This is duality, "Whether this or that?"
But one who is firmly convinced . . . vyavasāyātmikā buddhir ekeha kuru-nandana (BG 2.41). One who is firmly convinced that kṛṣṇe bhakti kaile sarva-karma kṛta haya: "If I become Kṛṣṇa conscious, then every perfection is there," this conviction, then there is no duality, "Whether I shall do it or not do it?" "I must do it." Dvandva. And moha, and illusion. And except Kṛṣṇa consciousness, everything is moha, illusion, except Kṛṣṇa consciousness. All illusion.
