Devotees: All glories to Śrīla Prabhupāda.
Prabhupāda: Hare Kṛṣṇa. Sāṅkhya-yoga is the aṣṭāṅga-yoga. This sitting posture and meditation, this is called sāṅkhya-yoga. And jñāna-yoga means by, through philosophical process. By analytical process what is Brahman and what is not Brahman. Neti neti. That is jñāna-yoga. Just like Vedānta-sūtra, jñāna-yoga. You study Vedānta-sūtra, it says janmādy asya yataḥ (SB 1.1.1). They give one hint codes, that the Supreme Brahman, Absolute Truth is that from whom everything is emanated. Now we try to understand what must be that. That is explained in the Śrīmad-Bhāgavatam. What is nature of that Absolute Truth. The Absolute Truth, in the first verse of Śrīmad-Bhāgavatam it is said: janmādy asya yato 'nvayād itarataś cārtheṣv abhijñaḥ svarāṭ (SB 1.1.1). Now the Absolute Truth, if He is the supreme cause of all emanation, then what are the symptoms? The Bhāgavata said that he must be cognizant. He's not dead. He must be cognizant. And what kind of cognizance? Anvayād itarataś cārtheṣu. Just like I am cognizant, you are also cognizant. But I do not know myself, how many hairs are there in my body. I'm claiming this is my head. But if I ask anybody, "Do you know how many hairs you have got in your body?" That kind of knowledge is not knowledge. But the Supreme, Bhāgavata says that He knows everything directly and indirectly. I know I am eating, but I do not know how my eating process is helping my circulation of blood, how it is being transformed, how it is working, how it going through the veins. I do not know anything. But God must be He who knows everything - every corner of His creation what is going on He must know. Therefore the Bhāgavata explains, that Supreme Truth, from whom everything is emanated, He must be supremely cognizant. Cognizant. Abhijñaḥ, abhijñaḥ means cognizant.
That, you may question, "Then if He is so powerful, wise and cognizant, He must have learned it from similar..." No. We say that if he learns knowledge from somebody else, then he is not God. Svarāṭ. Automatically. He's self-independent. This is jñāna-yoga. The study, what is the nature by… Just analyze what should be the nature of the supreme from whom everything is emanating. That is explained in the Śrīmad-Bhāgavatam. Therefore Śrīmad-Bhāgavatam is the supreme jñāna-yoga and bhakti-yoga combined. Jñāna-yoga process means to search out the Absolute Truth, or to understand the nature of the Absolute Truth by philosophical way. And this is called jñāna-yoga. And our is bhakti-yoga. Bhakti-yoga means, the process is the same, target is the same. One is trying to reach the supreme ultimate goal by philosophical way, one is trying to concentrate his mind on the supreme and the other, the bhaktas, they are simply engaging themselves to serve the Supreme Lord so He reveals. One process is to understand by the ascending process. And another process is the descending process. Just like in darkness, if you try to understand what is sun by ascending process, by flying your very powerful airplane or sputniks, just go round over the sky, you cannot see. But the descending process, when the sun rises, you understand immediately. Ascending process - my endeavor, what is called inductive process. Inductive process. Just like my father says that man is mortal. I accept it. Now if you want to study whether man is mortal, you study, you see many thousands of men, whether he is immortal or mortal. That will take so much time. But if you take the knowledge from the superior authority, that man is mortal, your knowledge is complete.
So athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi jānāti tattvaṁ bhagavan-mahimno na cānya eko 'pi ciraṁ vicinvan (SB 10.14.29). Therefore it is said, "My dear Lord, a person who has received a little favor from You, he can understand You very quickly. And others who are trying to understand You by the ascending process, they may go on speculating for millions of years, they will never understand." They will never understand. They will come to the point of frustration and confusion. "Oh, God is zero." That's all, finished. You see? If God is zero, then how from zero so many, I mean to say, figures coming out? God is not zero. Bhāgavata says, Vedānta says janmādy asya yataḥ (SB 10.14.29). Everything is, generates, from the Supreme. Now we have to study how it is generated. That is also explained, what is the way, what is the process, how to know it. This is Vedānta-sūtra. Vedānta means the ultimate knowledge. Veda means knowledge and anta means ultimate. So Vedānta means the ultimate knowledge. The ultimate knowledge is the Supreme Lord.
