vidyāṃ cāvidyāṃ ca yas tad vedobhayaṃ saha / avidyayā mṛtyuṃ tīrtvā vidyayāmṛtam aśnute //
Plain EnglishOne who knows both knowledge and ignorance together — crossing death through ignorance, attains immortality through knowledge.
Layer 2 — What it means
The resolution of the paradox set up in verses 9–10. Both together — not one or the other. Through avidyā (here: ritual action, practical engagement with the world) one crosses death — meaning: one does not simply withdraw from life prematurely, one fulfils one's human obligations, one completes the practical arc of a life. Then through vidyā (the knowledge of the self as Brahman) one attains immortality — the recognition that the self is not born and does not die.
The Upaniṣad is not prescribing a two-stage sequential path. It is saying that both orientations must coexist: the practical engagement with the world (which includes ritual, ethics, relationships) and the knowledge of what the world's ground is. The person who has only the first never reaches liberation. The person who has only the second without practical preparation is ungrounded.
Reading this page will give you the concept clearly. But the Upanishads were not written to be understood the way you understand chemistry or history. They were written to point toward something you can only recognise in yourself. That recognition is not on this page. This page only clears the way.

Layer 2 — Philosophical meaning
Śaṅkara's reading is contested. His bhāṣya: avidyā = karma and upāsanā (ritual and meditation) purify the mind and prepare it for knowledge; vidyā = jñāna of Brahman then produces liberation directly. The verse is then sequential: ritual crosses death (avoids premature death, fulfils dharma), knowledge attains liberation. Rāmānuja's reading: avidyā and vidyā are the lower and higher knowledges described in Muṇḍaka 1.1 — the combination means a complete understanding of both the manifest and unmanifest aspects of Brahman. The verse has also been read as supporting the Bhagavad Gītā's synthesis of karma-yoga and jñāna-yoga.
