BG Chap 7 - After many births the jñānī becomes qualified

The jñānī, seeing Vāsudeva everywhere, after many births, surrenders unto Kṛṣṇa. Such a person attains the Lord thru association with devotees. That jñānī who is a devotee has a steady mind and is very rare. Out of thousands, one person may know the Lord in truth. But the kevala or ekānta bhakta is very, very rare. Baladeva Vidyābhūṣaṇa says the three types of devotees (other than the jñānī), by the power of performing bhakti to Kṛṣṇa, after experiencing the highest happiness from material pleasures for many lives, finally in one birth find these pleasures distasteful. By association with saintly persons they gain knowledge of the Lord’s svarūpa and surrender unto Kṛṣṇa. These three devotees become jñānīs after many births and attain Kṛṣṇa. One has to rise to the platform of niṣkāma and then from that level fully surrender to Kṛṣṇa. Bhakti is rare even among jñānīs and its development usually takes a long time. Association with pure devotees quickens the process, because by association one hears and chants about Kṛṣṇa, whose glories are the essence of transcendental knowledge.

The jñānī understands that Kṛṣṇa, the son of Vasudeva, is everything. All things in existence depend on Kṛṣṇa for their manifestation and continued existence in those forms. What is dependent for its form and continued existence on Him, is designated as Himself. In Chāndogya Upaniṣad, the prāṇa is designated as the voice and eye, because those things are all dependent on prāṇa for preservation of their forms. Since all things in existence are pervaded by Vāsudeva, Vāsudeva is everything. Vāsudeva is everything in the sense that everything is dependent on Him. Arjuna confirms later in chapter 11 of the Gītā that since Kṛṣṇa covers everything and thus He is everything.
