The Yoga of Knowledge

After showing how wandering senses destroy wisdom (2.67), Krishna offers the solution. 'Yasya nigṛhītāni sarvaśaḥ indriyāṇi'—whose senses are completely withdrawn. But nigṛhīta doesn't mean suppressing senses or avoiding life. Your eyes see, ears hear, but they don't hijack your mind. 'Tasya prajñā pratiṣṭhitā'—that person's wisdom stays steady. This is the sthita-prajña (2.54) in action. How? Through rāga-dveṣa-viyukta (2.64): when free from attachment and aversion, sense objects lose their power to pull you around. You engage fully with life, but your mind isn't enslaved to every stimulus.
