Devotees always succeed where materialists fail because they surrender to Krishna's will rather than chase selfish desires.Listen — Srila Prabhupada Uvaca
Prabhupāda: ...between karmī and bhakta. Hmm? Śukadeva: The bhakta has no desires to fulfill, whereas the karmī has unlimited desires to fulfill. Puṣṭa Kṛṣṇa: The bhakta desires to carry out the order of Kṛṣṇa, and the karmī is interested in satisfying himself, gratification of the senses.
Prabhupāda: Karmī is also working and bhakta is also working. Then what is the difference? Hari-śauri: One is working for his own sense satisfaction and the other is working for the sense satisfaction of Kṛṣṇa. Puṣṭa Kṛṣṇa: Mentality?
Devotee (1): The devotee is peaceful. The karmīs are never peaceful.
Prabhupāda: Karmī... Just like I began this Kṛṣṇa consciousness business with forty rupees, eh, in New York. Now, say within eight or ten years, we have got forty crores. What is the karmī who started his business with forty rupees and within ten years, eight years, has got forty crores?
Puṣṭa Kṛṣṇa: Therefore the difference is the karmī's not successful.
Prabhupāda: A bhakta is never unsuccessful. Devotee (2): His results are temporary. Our results are eternal. Prabhupāda: Yes. Karmī... Just like this house you have got.
For a karmī to invest so much money, it will takes fifty years. We got it offered by someone. [laughter] Hari-śauri: Nobody's going to come up to a karmī and give him six hundred thousand. Prabhupāda: To acquire $600,000.-, for a karmī it will require six hundred years. [laughter] For a bhakta, somebody comes, "Take it," immediately.
