Bhagavad Gita
18.50

सिद्धिं प्राप्तो यथा ब्रह्म तथाप्नोति निबोध मे | समासेनैव कौन्तेय निष्ठा ज्ञानस्य या परा ||

siddhiṁ prāpto yathā brahma tathāpnoti nibodha me samāsenaiva kaunteya niṣṭhā jñānasya yā parā

Translation

Learn from Me briefly, O Arjuna, how one who has attained perfection reaches Brahman — that which is the supreme culmination of knowledge.

Interpretation

Having described the perfection that can be attained through one's own svadharma, Krishna now promises to describe concisely how the perfected one attains Brahman itself — the supreme, the Absolute. This is the final ascent: from proper action (svadharma performed with devotion) to inner perfection (naishkarmya-siddhi) to Brahman-realization. The Gita's complete path is revealed: action → purification → inner freedom → Brahman-knowledge → liberation.
