Shree Krishna had mentioned earlier in verse 7.26 that no one can know God by the strength of their own intellect. However, in this verse, He says that God can be known—only by virtue of His grace. Those devotees who surrender to Him completely—receive His divine grace. The Kaṭhopaniṣhad states
nāyamātmā pravachanena labhyo  na medhayā na bahunā śhrutena
yamevaiṣha vṛiṇute tena labhya-stasyaiṣha ātmā vivṛiṇute tanūṁ svām
(1.2.23) [v29]
“God cannot be known—through spiritual discourses nor the intellect nor hearing various kinds of teachings. Only when He bestows His grace upon someone does that fortunate soul come to know Him.”
The Vedas state
ekasmin vijñāte sarvamidaṁ vijñātaṁ bhavati
[v30]
“If you know God, you will know everything.”
Although some spiritual seekers consider
ātma-jñāna,
or knowledge of the self, as the ultimate goal of human birth, it is only a tiny drop in the ocean of knowledge, which is
brahma-jñāna
or the knowledge of God. By just knowing a drop, one cannot understand the enormity, depth, or prowess of the ocean. Therefore,
ātma-jñāna
cannot be in any way equal to
brahma-jñāna.
However, it can be a starting point toward the absolute.
According to the Vedas, absolute knowledge is—the Knowledge of God. If you know God, everything related to Him; is also revealed, and all your ignorance disappears. Shree Krishna states that those who take His shelter are liberated from the cycle of birth and death forever. And by His divine grace, they receive
brahma-jñāna
or knowledge of the
Brahman, ātma-jñāna
or knowledge of the self and the entire field of karmic action or the divine laws of karma.
