Prabhupāda: Although He's equal to everyone, He's specially, I mean, inclined, favorable to the devotees. Teṣām eva anukampārtham aham ajñāna-jaṁ tamaḥ. There . . . He takes special care. He says, samo 'haṁ sarva-bhūteṣu (BG 9.29). Although He's equal to everyone, still He's specially inclined to the devotees. For the devotees, he gives special instruction from within. Yena mām upayānti te. This is the special advantage of a devotee.
Go on.
Pradyumna: "Therefore, because of the Personality of Godhead taking charge of illuminating the heart of His devotee, certainly a devotee engaged in His service in transcendental love cannot remain in darkness."
Prabhupāda: So there is no question that a devotee will remain in darkness. Sometimes it is argued that mostly devotees are not very much educated. It doesn't matter. This external, academic education has no value for spiritual advancement. So here it is said, ahaṁ nāśayāmy ātma-bhāvasthaḥ (BG 10.11). Kṛṣṇa is within everyone, and if every . . . anyone is purified, Kṛṣṇa takes charge and He instructs. And who can be greater instructor than Kṛṣṇa? Therefore it is a wrong theory that devotees are ignorant. They're full of knowledge. If one is actually a devotee, there is no lack of knowledge. That's a fact.
Go on.
Pradyumna: "He comes to know everything of the absolute and the relative truths. The devotee cannot remain in darkness, and because a devotee is enlightened by the Personality of Godhead, his knowledge is certainly perfect. This is not the case for those who speculate on the Absolute Truth by dint of their own limited power of approach."
Prabhupāda: Yes. One can speculate about the Absolute Truth to certain extent. Therefore, generally, these speculators becomes impersonalists. Because they cannot go beyond that. But that impersonal knowledge is not complete. As we have several times stressed on this point, one has to go further, onward—realization of Paramātmā, realization of the Supreme Personality of Godhead. But they stop only in impersonal view. That's all.
