This is the brahma position, oh Pārtha. Having attained it, one is not confused. Established in it at the end, one reaches cessation in Brahman

The final synthesis: eṣā (this, all the previous teaching) is brāhmī sthitiḥ (position of Brahman, stability in the absolute). It is not an emotional state but an ontological one.

Prāpya (having attained) na vimuhyati (one is not confused). Confusion (moha) cannot touch one established in truth.

Anta-kāle (at the final moment, death) sthitvā (having remained) asyām (in this) brahma-nirvāṇam ṛcchati (one reaches cessation/extinction in Brahman). Nirvāṇa is mokṣa — final liberation from saṃsāra.
