BG 7.2: I shall now reveal unto you fully this knowledge and wisdom, knowing which nothing else remains to be known in this world.


Knowledge that is acquired through the senses, mind, and intellect is called jñāna. Knowledge that comes as insight from within, as a consequence of spiritual practice, is called vijñāna (wisdom). Vijñāna is not intellectual knowledge; it is direct experiential realization. For example, we may keep hearing about the glories of the sweetness of honey kept in a bottle, but it remains theoretical knowledge. However, when we open the lid of the bottle and taste the honey inside, we get experiential realization of its sweetness. Similarly, the theoretical knowledge we get from the Guru and the scriptures is jñāna. And when, in accordance with that knowledge we practice sādhanā and purify our mind, then the knowledge that awakens within us as realization is called vijñāna.

When Sage Ved Vyas decided to write the Śhrīmad Bhāgavatam describing the nature, glories, and object of devotion, he was not content to write it on the basis of jñāna, and so he first engaged in bhakti to get experiential realization of God:

bhakti-yogena manasi samyak praṇihite ’male

apaśhyat puruṣhaṁ pūrvaṁ māyāṁ cha tad-apāśhrayām (Bhāgavatam 1.7.4)[v1]

Through bhakti yog, Ved Vyas fixed his mind upon God, without any material sentiments, and thus he attained complete vision and realization of the Supreme Divine Personality along with his external energy, Maya, which was under his control.” Equipped with this realization, he then wrote the famous scripture.

Shree Krishna declares that he will illumine Arjun with the theoretical knowledge of the Supreme Divine Personality, and also help him gain the inner wisdom regarding it. On realization of this knowledge, nothing further will remain to be known.
