So Prahlāda Mahārāja says that viprād dvi-ṣad-guṇa-yutādaravinda-nabha. Even a brāhmaṇa, qualified brāhmaṇa who has all these brahminical qualifications, but he is not a devotee of the Lord... There are many good, qualified persons, but they do not on of the Supreme Personality of Godhead. Materially, one may be very much highly qualified. Academically, one may be very highly qualified. But if one is not a believer, faithful, or is not accepting the existence of God, or God the Supreme, he is called atheist, and Prahlāda Mahārāja does not say atheist, but he says that "Even one has got all these good qualifications, but if he is not qualified with the faith in God, or not becoming a devotee of God, then he is nonqualified. He is rejected." You may take his qualification in consideration, but Prahlāda Mahārāja says he is rejected from Kṛṣṇa consciousness for that one disqualification, that he is not a devotee of God. Similarly, in other places it is also confirmed that yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇais tatra samāsate surāḥ: "If one is simply unflinching faithful devotee of the Lord, then he develops all the good qualification of demigods." Harāv abhaktasya kuto mahad-guṇā: SB 5.18.12 "If one is not devotee of the Lord, then he has no good qualification." Why? Because manorathenāsato dhāvato bahiḥ: "Because he is hovering on the mental plane." And because he is hovering on the mental plane—the mind's business is to change—so he will change from one platform to another, another platform to another. He has no fixed idea; therefore his qualification has no value. In several places In the Bhagavad-gītā Lord Kṛṣṇa says, api cet su-durācāro bhajate mām ananya-bhāk: "If a person is found even unclean or not very well behaved but he has got unflinching faith in Me, Kṛṣṇa," sādhur eva sa mantavyaḥ SB 5.18.12 , "oḥ, he is sādhu. He is saintly person." He is saintly because that one qualification, that he has full faith in God, Kṛṣṇa, that one qualification makes him a saintly person. Others may have all the good qualification, but simply for one minor godlessness, he is nonqualified.
So Prahlāda Mahārāja confirms the same statement. Prahlāda Mahārāja is also a sādhu because he is a devotee. Narottama dāsa Ṭhākura has said that if you want to make concrete progress in spiritual life, then you have to corroborate the statement of the scriptures, the statements of saintly person, and statements of the spiritual master-three things. Why three things? Because a spiritual master means he does not place anything which is not in the scriptures. He does not say that "My theory is like this." That is not a spiritual master. Similarly sādhu, saintly person, also does not say anything which is not mentioned in the scriptures. He does not manufacture anything by mental concoction. And what is śāstra, scriptures? They are statement of different saintly persons and spiritual masters. Therefore one has to corroborate these three things: scriptures, and statement of saintly persons, and statement of spiritual master. The spiritual master is via media. The disciple, if he cannot understand the statement of the scriptures or any saintly person, he submits his doubts before the spiritual master and he clears it. In this way we have to make progress. So Prahlāda Mahārāja says that a person, even if he is a brāhmaṇa with good qualification, if he is not a devotee of the Lord, then he is good for nothing. He says, "He is good for nothing." Viprād dvi-ṣad-guṇa-yutāt. And when who is good? Now, śvapacaṁ variṣṭham. Better than him, even a person is born of a very low family... In India it is considered according to Vedic, that low family is considered one who eats the dog, dog-eaters. Of course, there are many kinds of flesh-eaters, but when a man becomes the eater of dog flesh, he is considered to be very low. So śvapacaṁ variṣṭham. So there is a class in India, they are called caṇḍāla. Everywhere there is. They eat dog flesh. So Prahlāda Mahārāja says, "It doesn't matter. But if he is a devotee of Lord, he is better than that brāhmaṇa, that brāhmaṇa with good qualifications. And he, although he is born of a low family..." Śvapacaṁ variṣṭham. Why he is variṣṭham? Now, manye tad-arpita-mano: "Because his mind and attention is always engaged in the service of the Lord." That is his qualification. That is making him purified in every moment.
