- mayy āsakta-manāḥ pārtha
- yogaṁ yuñjan mad-āśrayaḥ
- asaṁśayam samagraṁ māṁ
- yathā jñāsyasi tac chṛṇu
- (BG 7.1)
So by the end of the Sixth Chapter, Kṛṣṇa has explained the aṣṭa, aṣṭāṅga-yoga-siddhi. Aṣṭāṅga-yoga-siddhi, that yoginām api sarveṣāṁ mad-gatenāntar-ātmanā (BG 6.47): always who is thinking of Kṛṣṇa within himself, śraddhāvān, with faith and knowledge, he is first-class yogī.
So how this first-class yoga system helps me? Because the other yoga system, they will disagree that, "Simply by thinking of Kṛṣṇa within one's heart, how one becomes perfect?" That is explained from the Seventh Chapter of Bhagavad-gītā, how simply by understanding Kṛṣṇa you become well aware of everything, this yoga system. In the Vedas also it is stated, yasmin vijñāte sarvam idaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). If you, if you simply understand Kṛṣṇa, then you know everything.
Kṛṣṇa is the root of everything. Therefore Kṛṣṇa says, śrī-bhagavān uvāca. We should always remember that this Bhagavad-gītā is being spoken by the Supreme Personality of Godhead. So no more better authority. And God is speaking about Himself. Otherwise, by speculation you cannot understand God. That is not possible. You have to hear from God Himself about God.
- athāpi te deva padāmbuja-dvaya-
- prasāda-leśānugṛhīta eva hi
- jānāti tattvaṁ bhagavan . . .
- na cānya eko 'pi ciraṁ vicinvan
- (SB 10.14.29)
"A person who has got little favor," athāpi te deva padāmbu . . . "little favor from the lotus feet of Your Lordship, he," jānāti tattvam, "he knows what is tattva, what is the Absolute Truth." Athāpi te deva padāmbuja-dvaya-prasāda-leśānu . . . prasāda-leśa: little favor, not all. Prasāda-leśānugṛhīta eva hi jānāti tattvam, na ca anya ciraṁ vicinvan. Others may go on speculating for years and years, it is not possible to understand.
