Bhagavad Gita Chapter 14, Verse 1

श्रीभगवानुवाच | परं भूयः प्रवक्ष्यामि ज्ञानानां ज्ञानमुत्तमम् | यज्ज्ञात्वा मुनयः सर्वे परां सिद्धिमितो गताः ||

śrī-bhagavān uvāca paraṁ bhūyaḥ pravakṣyāmi jñānānāṁ jñānam uttamam yaj jñātvā munayaḥ sarve parāṁ siddhim ito gatāḥ

The Blessed Lord said: I shall again speak to you of the supreme knowledge, which is the highest of all knowledge. Knowing this, all sages have attained supreme perfection from this world.

Krishna introduces Chapter 14 with a profound promise: 'Paraṁ bhūyaḥ pravakṣyāmi'—I shall speak to you again of the supreme knowledge. 'Jñānānāṁ jñānam uttamam'—the highest of all knowledge. This isn't just another teaching—it's the knowledge that transforms. 'Yaj jñātvā munayaḥ sarve parāṁ siddhim ito gatāḥ'—knowing this, all sages have attained supreme perfection (parāṁ siddhim) from this world. Krishna is about to reveal the knowledge of the three gunas (sattva, rajas, tamas)—the three modes of material nature that bind the soul. This understanding is the highest knowledge because it reveals how material nature works, how you're bound, and how to transcend. Without understanding the gunas, you remain trapped in the cycle of material existence. But with this knowledge, you can recognize which mode is active and rise above them all.
