Verse:
- tvam ādyaḥ puruṣaḥ sākṣād
- īśvaraḥ prakṛteḥ paraḥ
- māyāṁ vyudasya cic-chaktyā
- kaivalye sthita ātmani
- (SB 1.7.23)
So, we have to know the Supreme Personality of Godhead through authority, not by speculation. Speculation is no use.
- athāpi te deva padāmbuja-dvaya-
- prasāda-leśānugṛhīta eva hi
- jānāti tattvaṁ bhagavan-mahimno
- na cānya eko 'pi ciraṁ vicinvan
- (SB 10.14.29)
The Supreme Personality of Godhead can be known by a person who has got a slight favor of the Lord upon him. This is the Vedic version. Nāyam ātmā pravacanena labhyo na medhayā na bahunā śrutena. Ātmā, the Supreme Absolute Truth, cannot be understood... Nāyam ātmā na pravacanena labhyaḥ... By becoming a great debater one can understand the Supreme—that's not possible. Nāyam ātmā pravacanena labhyo na bahunā śrutena. Nor by a person who is very vastly learned or by a great scientist or philosopher, na medhayā—in this way we cannot understand. But one who is surrendered, he can understand. Arjuna is surrendered. In every case he surrendered to Kṛṣṇa. As soon as there is any problem... Problem or no problem, he surrendered. Not that "When there is problem I am surrendered, and when there is no problem I am independent." No. Always surrendered. That is Arjuna's position.
