Yajur-Veda (Śukla) · 18 mantras · the shortest of the Mukhya · also called Īśāvāsya Upaniṣad

2. केनोपनिषद् · Kenopaniṣad

Sāma-Veda · 34 mantras across 4 khaṇḍas

Central teaching: The question that every seeker asks: BY WHOM is the mind willed? By whom does prāṇa breathe first? By whom is the eye seeing? Kena reveals that Brahman is what makes seeing-seeing, hearing-hearing — the senses cannot reach Brahman directly … → read more →

4. प्रश्नोपनिषद् · Praśnopaniṣad

Atharva-Veda · 67 mantras · 6 questions answered by Pippalāda

5. मुण्डकोपनिषद् · Muṇḍakopaniṣad

Atharva-Veda · 64 mantras across 3 muṇḍakas

Central teaching: Distinguishes parā-vidyā (the higher knowledge of the imperishable Brahman) from aparā-vidyā (the lower knowledge of the 4 Vedas, śikṣā, kalpa, vyākaraṇa, nirukta, chandas, jyotiṣa). Both are vidyās, but only parā-vidyā liberates. The Muṇḍa… → read more →

6. माण्डूक्योपनिषद् · Māṇḍūkyopaniṣad[MAHĀ-VĀKYA]

Atharva-Veda · 12 mantras (shortest by mantra-count · most compressed teaching of all)

Mahā-vākya: अयमात्मा ब्रह्म · ayam ātmā brahma — THIS ĀTMĀ (Self) IS BRAHMAN

Central teaching: The Māṇḍūkya is the most compressed Upaniṣad — 12 mantras that contain the entire teaching of the four states of consciousness mapped to the four parts of OM: (a) jāgrat-vaiśvānara · the waking state · "a"; (u) svapna-taijasa · the dream st… → read more →

8. ऐतरेयोपनिषद् · Aitareyopaniṣad[MAHĀ-VĀKYA]

Ṛg-Veda · ~33 mantras across 3 chapters

Mahā-vākya: प्रज्ञानं ब्रह्म · prajñānaṁ brahma — CONSCIOUSNESS / PURE-AWARENESS IS BRAHMAN
