Gurukṛpā: This faith in the mundane religions, that cannot be called real faith?
Prabhupāda: No, that is faith, but because one is not intelligent, he takes irreligion as religion. He does not . . . he should be also very intelligent, faithful and intelligent. Not blind faith. He must be faithful, and intelligence . . . he must know what is actually religion. So therefore sādhu-saṅga (CC Madhya 22.83). Associate with sādhus means those who are actually on the platform. So if he associates with the sādhu—the sādhus accept Kṛṣṇa as the Supreme Personality of Godhead—he will get the understanding that Kṛṣṇa is the Supreme Lord. Then his faith becomes fixed up in Kṛṣṇa. This is the way.
Gurukṛpā: So what is the exact meaning of that verse, śraddhā-śabde? That verse . . .
Prabhupāda: Yes, śraddhā. That faith increase, and when it is increased so much that he fully understands, "By worshiping Kṛṣṇa, everything is done," that is first-class faith. Śraddhā-śabde viśvāsa kahe sudṛḍha niścaya (CC Madhya 22.62). If he becomes fixed up, "Yes, Kṛṣṇa is the Supreme Personality," that is first class, means fulfillment of faith. In the beginning it might be doubtful, neophyte. But when that is . . . that faith is fixed up, "Yes, Kṛṣṇa is the Supreme Personality," that is the fulfillment of faith. Faith also there are different stages, improvement. Devotional service means different grades of faith. Today I am in one stage of faith, next day another stage, next day another stage, next day another stage. And when you come to the stage that vāsudevaḥ sarvam iti (BG 7.19), oh, that is final. Sa mahātmā sudurlabhaḥ. That takes time. And quickly also, if one is fortunate. If one is intelligent—"The śāstra says: 'Vāsudeva is everything,' so why not take Vāsudeva as everything?"—then he gains the result immediately. And if he thinks, "All right, let me see for some time," so he may waste his time, but the point is the same. Point is the same, but he has not developed his faith to such extent. He'll have to wait. And intelligent person, he says: "Why shall I wait? Let me take finally vāsudevaḥ sarvam iti (BG 7.19). That business is finished." Sa mahātmā. Therefore it is said, sa mahātmā sudurlabhaḥ.
That kind of staunch faith is not very easy. It is for the great personality. Immediately accepts. Kṛṣṇa says, sarva-dharmān parityajya (BG 18.66). Immediately accepts: "Yes." Then sa mahātmā sudurlabhaḥ. That is not very easily done. That means yeṣāṁ tv anta-gataṁ pāpaṁ janānāṁ puṇya-karmaṇām (BG 7.28). He is completely free from all reaction of sinful life. Puṇya-karmaṇām—he is only engaged in pious activities. Yeṣāṁ tv anta-gataṁ pāpaṁ janānām, te dvandva-moha . . . he has no more, I mean, doubt. Dvandva-moha-nirmuktāḥ. He has no doubt, "Yes, Kṛṣṇa is the Supreme Person." That's it. That's all. If you take by argument, reason, you may waste your time. But if you are intelligent, you can take it on the evidence of mahājano yena gataḥ, all the mahājanas.
