Chapter 15 · Verse 15
अयं सोऽहमयं नाहं विभागमिति सन्त्यज
ayaṃ so'hamayaṃ nāhaṃ vibhāgamiti santyaja | sarvamātmeti niścitya niḥsaṅkalpaḥ
‘This is that, this is not that’ — abandon such division (vibhāga). Having concluded that all is the Self, be free from conceptual thought (niḥsaṅkalpa). The teaching moves from understanding to practice: cease all mental division and abide as the undivided Self.
