Shloka 22
Brahma-vidyā: Satya–Tapas and the Enumeration of Tattvas
Arjuna–Vāsudeva framed dialogue
अजीव: सर्वभूतानां ब्रह्मबीज: सनातन: । एतजज्ञात्वा च तत्त्वानि ज्ञानेन परमासिना
ajīvaḥ sarvabhūtānāṁ brahmabījaḥ sanātanaḥ | etaj jñātvā ca tattvāni jñānena paramāsinā
风神伐由说道：“不坏之理，乃一切众生之中梵（Brahman）的永恒种子。知此之后，当以慧分别诸真实相，并以至上智慧之剑斩断迷妄——使人得以明澈而住，克己自持，具正见而行。”

Educational Q&A
That an eternal, imperishable principle underlies all beings and is the ‘seed’ leading to Brahman-realization; by recognizing this and discerning the tattvas, one uses knowledge as a ‘supreme sword’ to cut ignorance and live rightly.
Vāyu-deva is speaking in a didactic passage, delivering a metaphysical instruction: he points to the eternal principle present in all beings and urges the listener to employ discriminative knowledge to penetrate the truth of reality.
