Sanskrit
योऽन्तःसुखोऽन्तरारामस्तथान्तर्ज्योतिरेव यः । स योगी ब्रह्मनिर्वाणं ब्रह्मभूतोऽधिगच्छति ॥

Translation
He who is happy within, who rejoiceth within, who is illuminated within, that Yogî, becoming the Eternal, goeth to the Peace of the Eternal.

Explanation
Three inward-facing compounds stack up in a row — happy within, delighting within, lit within — building a portrait of self-sufficiency so complete that the outer world stops functioning as a reference point at all. Brahma-bhūta, “having become Brahman,” is a striking claim of identity rather than proximity or resemblance, and brahma-nirvāṇa names the peace that attends it — nirvāṇa appearing here centuries before its more famous Buddhist usage, meaning something closer to the extinguishing of a sense of separateness than annihilation. This verse is doing double duty as both a description of the realized state and a preview of what chapter 6 will spend its middle verses teaching someone how to reach.
