Bhagavad Gita
14.1

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

Translation

The Blessed Lord said: I shall again declare that supreme knowledge, the best of all knowledge, knowing which all the sages have gone from this world to the highest perfection.

Interpretation

Krishna opens Chapter 14 by announcing that he is about to share the highest of all knowledge — the teaching of the three gunas. This is the same knowledge by which all the great sages of antiquity attained liberation. The repetition of 'again' signals that this is a deepening of earlier teachings. Supreme knowledge here is not intellectual information but the direct understanding of nature's three constituent forces — sattva, rajas, and tamas — and how transcending them leads to freedom.
