Chapter 7 of the Bhagavad Gita, entitled 'Vijnana Yoga' or the 'Yoga of Knowledge and Realization,' focuses on the distinction between theoretical knowledge (jnana) and practical application (vijnana) of wisdom as it relates to understanding the absolute reality and Krishna's role as the supreme being. The chapter outlines the process of knowing Krishna, the nature of the material and spiritual energies, and the importance of surrendering to him, classifying humanity into different categories based on their spiritual pursuits. Key themes include the relationship between knowledge and devotion, the rarity of true devotees, and the awareness that everything ultimately derives from Krishna.
