Muṇḍaka Upaniṣad · 3.1.8
यस्तु विज्ञानवान् भवति समनस्कः सदा शुचिः । स तु तत्पदमाप्नोति यस्माद्भूयो न जायते
yas tu vijñānavān bhavati samanaskaḥ sadā śuciḥ | sa tu tat padam āpnoti yasmād bhūyo na jāyate
But whoever is endowed with discrimination, with balanced mind, ever pure — he reaches that goal from which he is not born again.
The result of practice: definite liberation.
Samanaskaḥ — with balanced mind, united. The stable mind, not scattered, concentrated.
Sadā śuciḥ — ever pure. Purity as a result of discrimination and control.
Tat padam āpnoti — reaches that goal. The purpose of the journey, the realization of the Self.
Yasmāt bhūyo na jāyate — from which one is not born again. Definite liberation, end of saṃsāra.
The contrast with the previous verse is total: the discriminating reaches the goal, the undiscriminating keeps spinning. The goal is Brahman, and reaching it is to know that one was never separate from it.
Complete yoga culminates here: no more chariot, no more journey, only the Self in its luminous immobility.
