Kṛṣṇa says, jñānaṁ te 'haṁ sa-vijñānam. This knowledge, with practical understanding, sa-vijñānam. Vijñānam means practical application. We understand Kṛṣṇa as the Supreme. He's the creator of this cosmic manifestation. He's the Supreme. We are all subordinate. This is jñānam. And sa-vijñānam, when it is practically applied, that means when you take to devotional service, then it is practically application, practicing.
- jñānaṁ te 'haṁ sa-vijñānam
- vakṣyāmy aśeṣataḥ
- yaj jñātvā neha bhūyo 'nyaj
- jñātavyam avaśiṣyate
- (BG 7.2)
So when we understand perfectly, complete knowledge, then there is no more anything remains to be understood. Everything is . . . tasmin vijñāte sarvam idaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3).
So the Bhagavad-gītā is not theory. It is knowledge, and practically applicable in life. Sa-vijñānam. And if we try to understand Kṛṣṇa in perfect order, then there is nothing remains to be understood. Everything becomes revealed. This knowledge becomes revealed. Nāhaṁ prakāśaḥ sarvasya yogamāyā-samāvṛtaḥ (BG 7.25). Revealed. Athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi (SB 10.14.29).
So we have to receive this knowledge submissively. The . . . Lord Brahmā recommends that jñāne prayāsam udapāsya namanta eva. Namanta eva. We must be submissive. The whole thing depends, spiritual knowledge . . .
- tad-vijñānārthaṁ sa gurum evābhigacchet
- samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham
- (MU 1.2.12)
Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34).
So this knowledge, this process of knowledge, is received by submissive mood. Jñāne prayāsam udapāsya. One has to give up the false prestigious position that, "I can understand God and everything by my speculative, experimental knowledge." This is called jñāne prayāsam. Jñāne prayāsam udapāsya namanta eva. One should be submissive, san-mukharitāṁ bhavadīya-vārtām, and try to hear the message of the Lord from san-mukharitām, sādhu, devotees, san-mukha . . . not professional. Śrī Sanātana Gosvāmī has strictly forbidden:
- avaiṣṇava-mukhodgīrṇaṁ
- pūtaṁ hari-kathāmṛtam
- śravaṇaṁ naiva kartavyaṁ . . .
- (Padma Purāṇa)
Avaiṣṇava, those who are not practically Vaiṣṇava, devotee, in practical life, professional person, there is no use. Avaiṣṇava. There must be heart and soul Vaiṣṇava.
Avaiṣṇava-mukhodgīrṇaṁ pūtaṁ hari-kathāmṛtam. Hari-kathā, the words about the Supreme Personality of Godhead, certainly that is amṛtam. But it still, it should not be heard from a person who is not a devotee.
