Jnana-Vijnana Yoga is the seventh chapter of the Bhagavad Gita, in which Lord Krishna explains the relationship between knowledge and wisdom, and how this knowledge can lead to liberation.
The chapter begins with Arjuna asking Lord Krishna to explain the difference between knowledge and wisdom, and how to attain true wisdom. Lord Krishna responds by explaining that knowledge is the understanding of the scriptures, while wisdom is the realization of the Supreme Self. He goes on to say that true wisdom can only be attained by those who have complete faith in the Supreme, are completely surrendered to Him, and have control over their senses.
Lord Krishna then explains the nature of the Supreme Self, saying that it is eternal, all-pervading, indestructible, and beyond the senses. He says that those who have realized this truth are freed from the cycle of birth and death, and attain eternal peace and happiness.
Lord Krishna also talks about the importance of detachment and renunciation in the path of knowledge, saying that those who are attached to material pleasures cannot attain true wisdom. He encourages Arjuna to be steadfast in his practice of yoga, and to always keep his mind fixed on the Supreme.
Overall, the Jnana-Vijnana Yoga chapter emphasizes the importance of knowledge, wisdom, detachment, and devotion in the path of spiritual liberation. It teaches that true wisdom can only be attained through the grace of the Supreme, and that those who have attained it are liberated from the cycle of birth and death, and attain eternal peace and happiness.
