Prabhupāda: Yes. So this bhakti-yoga means to know God, at the same time, practically employ yourself in the service of God, or in the transaction between God and yourself. That is vijñānam. Sa-vijñānam.
Indian man (1): What is the distinction between jñāna and vijñāna?
Prabhupāda: Jñāna means theoretical knowledge, and vijñāna means practical knowledge. Simply to know "God is great," that is not sufficient.
Indian man (1): No, that is theoretical.
Prabhupāda: Yes, that is theoretical. You must know how great He is. That we have to learn from the śāstras, from the guru, how great He is. Just like in the Brahma-saṁhitā, Vedic, yato vā imāni bhūtāni jāyante (Taittirīya Upaniṣad 3.1). He's the source of all material elements. In Him everything stays, and after annihilation, everything goes into Him. This is one understanding. Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13).
Mr. Sar: Eko bahūnāṁ vidadhāti kāmān.
Prabhupāda: In this way, from Vedas, from guru, from saintly persons, we have to understand. Sādhu guru śāstra vākya. Sādhu means who speaks strictly on the śāstra. Guru also speaks strictly on śāstra. Śāstra is the media. Yaḥ śāstra-vidhim utsṛjya vartate kāma-kārataḥ, na siddhim avāpno . . . (BG 16.23). Therefore we protest. Unless there is something mentioned in the authorized śāstras, we don't accept it.
Indian man (1): Is it nityaḥ anityānām or nityaḥ nityānām?
Prabhupāda: Nityo nityānām. Plural number.
Dr. Patel: Plural, yes.
Indian man (1): No, no, that's right.
Prabhupāda: Plural number.
Indian man (1): Permanent. Permanent, impermanent.
Prabhupāda: Both of them permanent. No, no, no. Permanent . . . the jīvas and the Supreme Lord, both of them are permanent, nityā. Na hanyate hanyamāne śarīre (BG 2.20). Just like nityaḥ śāśvato 'yam. It is said in the Bhagavad-gītā, nityaḥ śāśvato 'yam. Eternal, always existing. And this material world has been described: asasvataḥ. Duḥkhālayam aśāśvataḥ. Dr. Patel: Aśāśvatam.
Prabhupāda: Aśāś . . . it is not permanent. Bhūtvā bhūtvā pralīyate (BG 8.19). It appears and disappears. So because nityo nityānām, there is transaction between the nitya, the supreme nitya, Kṛṣṇa, and the . . .
Dr. Patel: Cetanaś cetanānām.
Prabhupāda: . . . and the subordinate nityas, the living entities. So there must be one place also where this transaction takes place. Because this is anitya. This material world is anitya. So how the transaction between the nitya and nityānām can take place? Because the place is anitya. Therefore there must be a place which is nitya. There must be place. That is Vaikuṇṭha dhāma, spiritual world. So by practicing bhakti-yoga scientifically, by practical understanding, practical application, yogaṁ yuñjan mad-āśrayaḥ, either at the shelter . . .
Mr. Sar: Anyaj jñātam neha bhūyo . . .
Prabhupāda: Eh?
Mr. Sar: Anyaj jñātam avaśiṣyate.
Prabhupāda: Ah. Then anyaj jñātavyam. No. Then you become perfect. No more knowledge.
Mr. Sar: No more knowledge is required.
Prabhupāda: Yes, knowledge is perfect.
Mr. Sar: Final
Prabhupāda: Final, yes.
Prabhupāda: Yasmin vijñāte sarvam etaṁ vijñātaṁ bhavanti (Muṇḍaka Upaniṣad 1.3). This is also Upaniṣad. Yasmin vijñāte. If you simply understand Kṛṣṇa, then sarvam eva vijñātaṁ bhavanti, then you have got full knowledge. And that is also stated in the Fourth Chapter: janma karma me divyam yo janāti tattvataḥ, tyaktvā dehaṁ punar janma naiti mām eti . . . (BG 4.9). He becomes immediately liberated. Simply if you understand Kṛṣṇa, what is Kṛṣṇa, tattvataḥ, in truth, then you are . . . your business is finished.
