Those who are actually budhās—budhās means learned—so they know Kṛṣṇa is the original person. And it is confirmed by Brahmā in the Brahmā-saṁhitā, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1). Īśvara. Īśvara means controller. So everyone can become īśvara. Here, our minister saheb is present. He's īśvara. Īśvara means controller. He is controller of a department. Similarly, there are many ministers in our country and other countries, many presidents. They are īśvaras. And a common man, he is also īśvara. He's controlling his family. At least he's controlling his dog, cat.
So everyone is īśvara. Just like the modern theory is going on, "Everyone is God." That's all right. God means īśvara, controller. But there are different qualities of controller. I may be controller of my disciples, a few dozen or few hundred. But there are controllers, millions. They are controlling millions. Therefore my control and his control is not equal. Therefore you find out one controller after another. Everyone is relative controller. He controls, and he becomes controlled. Nobody's absolute controller. Just like our minister saheb. He's controller, but he's also controlled.
So when you come to the point, if you find out some person that He's simply controller, not controlled, He's Kṛṣṇa. Kṛṣṇa is simply controller, not controlled. He's Kṛṣṇa. Kṛṣṇa is simply controller. When Kṛṣṇa was present on this planet—you see the history of His life—He simply controlled. He never became controlled. He was controller. Therefore the verdict of the śāstra, Vedic literature, is that īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1): the supreme controller is Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ.
But the impersonalists will say: "The supreme controller is not a person." He's a person. But Brahmā says, "No, He's a person." Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigraha. Vigraha means person. Mūrti. But He's not ordinary person. Sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Sat, cit, ānanda. His form is made of eternity, bliss and knowledge. Our form, this form, is not eternity. It will die. It will finish. Why my form? Even Brahmā's form, although he will live for many millions of years.
Just like one day, twelve hours, is described in the Bhagavad-gītā: sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). Brahmā's one day, twelve hours, he . . . these four yugas, forty-three hundred thousands of years multiplied by one thousand. That is Brahmā's twelve days, uh, twelve hours. Now we can calculate his life. He'll live for one hundred years. So his twelve hours is millions of years. So still, he will die. Anything in this material world, it will not stay. Bhūtvā bhūtvā pralīyate (BG 8.19). Everything will be finished. Therefore even Brahmā's body is not eternal, what to speak of my body, your body, ant's body, his body . . . sat. Sat means "that exists." Oṁ tat sat.
And cit. Cit means knowledge. So Kṛṣṇa's knowledge is perfect. Kṛṣṇa says, vedāham, vedāhaṁ samatītāni (BG 7.26): "I know past, present and future." When Kṛṣṇa was questioned by Arjuna, Kṛṣṇa said that "Many millions of years ago, first of all, I spoke this science of Bhagavad-gītā, or bhakti-yoga, to the sun-god." Imaṁ vivasvate proktaṁ, vivasvān manave prāha: "I spoke, first of all, to Vivasvān, the sun-god." The sun-god's name is there, Vivasvān. Then Kṛṣṇa was questioned by Arjuna that "Kṛṣṇa, You and me, we are born very recently. How is that You say that You spoke to sun-god? That is millions and millions of years ago."
So Kṛṣṇa answered, "Yes, I said. I remember; but you do not remember. You were also present." Kṛṣṇa and Arjuna, they're eternal friends. So whenever Kṛṣṇa appears, Arjuna also appears. Kṛṣṇa has got His associates. Arjuna is one of the associates. But the . . . that is the difference between living entity and God. God remembers and the living entity does not remember. He forgets. And another conclusion is: Why Kṛṣṇa remembers and why the living entity does not remember? The reason is the living entity changes the body; Kṛṣṇa does not change the body. Sambhavāmy ātma-māyayā (BG 4.6). When Kṛṣṇa appears, He appears in His original body, but because He looks like ordinary man, avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam (BG 9.11), the rascals and fools, they think Kṛṣṇa as ordinary man, human being.
