From the spiritual planet, Goloka Vṛndāvana, the glowing effulgence, brahma-jyoti, is coming out. How it is coming out? That we can very easily understand. As the sunshine is coming out, emanating incessantly from the sun disc, similarly the real sunshine, brahma-jyoti, is coming out of the spiritual planet Goloka Vṛndāvana incessantly. That is called brahma-jyoti. Yasya prabhā prabhavato (Bs. 5.40). And due to that incessant shining, all the shining which you are experiencing, even this lamp, even this electricity, fire, moonshine, sunshine, any shining, that is due to that brahma-jyoti.
So yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). In that shining, this material world, the spiritual world, they are resting. So impersonalist, they are concerned with the shining, that's all. The difference between the personalist and impersonalist is that impersonalist, they take that shining as final. But the personalist, they take, "No. Kṛṣṇa is final." That is their difference of opinion. Otherwise, both of them in the spiritual realm.
And so far Kṛṣṇa is the cause of brahma-jyoti, there are many evidences from Vedic literature. In Īśopaniṣad and other Upaniṣads, in Bhagavad-gītā also, the Lord says, brahmaṇaḥ ahaṁ pratiṣṭhā: "I am the source of brahma-jyoti." You'll find in the Fourteenth Chapter, last verse, brahmaṇaḥ ahaṁ jyoti.
(aside) Is there any Bhagavad-gītā? You find out Fourteenth Chapter, last verse (BG 14.27).
Satsvarūpa: The English?
Prabhupāda: Yes.
Satsvarūpa: "For I am the abode of Brahman, immortal, and the imperishable, of eternal law and of absolute bliss."
Prabhupāda: That's all? So He's the source of brahma-jyoti. So if we have such realization that Kṛṣṇa is absolute, and if we realize . . . it is a question of realization.
Now, when you chant Hare Kṛṣṇa, if we chant mechanically, then the effect is different. I have already given you the ten kinds of offenses there are in chanting Hare Kṛṣṇa. So mechanical way of chanting is also another offense. So offenseless chanting . . . of course in the beginning, neophytes, we are apt to commit so many offenses. But we should be careful that the chanting should be offenseless. Then we shall realize that Kṛṣṇa is present by His name. He is present. You'll realize, and you'll have the same effect as you expect by meeting Kṛṣṇa personally.
You can see Kṛṣṇa and you can hear Kṛṣṇa. Because Kṛṣṇa is absolute, there is no difference between seeing and hearing. That is the absolute sense. People give more stress on the eye, "Oh, can you show me Kṛṣṇa?" Oh, can't you hear Kṛṣṇa? Why do you give . . .? This is also one sense; that is also another sense. Do you think by seeing you'll understand everything? You are seeing so many things daily. Do you understand? So this is all foolishness that, "Can you show me?"
Now we have got so many senses. So perception through any sense, because He is absolute, the same effect. Either you see Him personally or you hear Him. Rather, hearing is better, because by seeing you cannot understand Kṛṣṇa. When Kṛṣṇa was present, all people saw Him, but they could not understand Kṛṣṇa. But one who heard of Kṛṣṇa even five thousand years after, just like we are hearing, we can understand Kṛṣṇa as far as possible. So hearing is most important thing. You'll find in the Thirteenth Chapter, śruti parāyaṇa (Gītār Gān 13.26). Śruti parāyaṇa. Śruti parāyaṇa means one who is very much eager to hear about Kṛṣṇa, he's a very nice qualified man.
