Chapter 10 · Verse 6

सर्वं ब्रह्ममयं ज्ञात्वा निर्द्वन्द्वो निर्भयो भव

sarvaṃ brahma-mayaṃ jñātvā nirdvandvo nirbhayo bhava

Knowing that all is Brahman, be free from duality (dvandva) and without fear. There is nothing to fear and nothing to lose. You are fullness, peace, and freedom. Chapter 10 closes with this truth as its seal. The abandonment of all is not an act of doing but an act of recognition: if all is Brahman, there is nothing to hold and nothing to release. Freedom from duality is the last word, for there is no subsequent chapter where something better might be sought.
