The Yoga of Liberation by Renunciation

Krishna introduces the teaching about transcending the gunas and attaining Brahman. 'Siddhiṁ prāpto yathā brahma tathāpnoti nibodha me'—understand (nibodha) from Me (me), how (yathā) one having attained perfection (siddhim prāptaḥ) attains (āpnoti) Brahman (brahma). 'Samāsenaiva kaunteya niṣṭhā jñānasya yā parā'—in summary (samāsena), O son of Kunti (kaunteya), which is the supreme (parā) establishment (niṣṭhā) in knowledge (jñānasya). This sets up the detailed teaching about how to transcend the gunas and attain the supreme goal—Brahman, the ultimate reality. This is the culmination: after performing one's duty with devotion and renunciation, one attains perfection and ultimately Brahman. This is the path: perfection through duty leads to Brahman, the supreme establishment in knowledge.
