🪷 MAHĀ-VĀKYA · GREAT-STATEMENT 🪷
अहं ब्रह्मास्मि
ahaṁ brahmāsmi
I AM BRAHMAN
— Bṛhadāraṇyaka 1.4.10

Central Teaching

The Bṛhadāraṇyaka contains the supreme Upaniṣadic dialogues of Yājñavalkya — with his queen Maitreyī (the famous "ātmā vā are draṣṭavyaḥ" teaching · "the Self alone is to be realized · all else is dear because of the Self"), with the brāhmaṇa King Janaka, and with the scholar Gārgī (the woman-philosopher who challenges Yājñavalkya in open court). The mahā-vākya "ahaṁ brahmāsmi" is the first-person realization-declaration. The closing pūrṇa-mantra "pūrṇam adaḥ" is also from Bṛhadāraṇyaka (5.1.1) — the same śloka that the Iśopaniṣad uses as its invocation.

Key Śloka

असतो मा सद्गमय। तमसो मा ज्योतिर्गमय। मृत्योर्मा अमृतं गमय।

asato mā sad gamaya · tamaso mā jyotir gamaya · mṛtyor mā amṛtaṁ gamaya

"From the unreal lead me to the real · From darkness lead me to light · From death lead me to immortality."

— Bṛhadāraṇyaka 1.3.28 (the universal śānti-mantra · chanted in every dharmic gathering)

🪷 Krishna-Tattva Connection

Krishna in BG 2.16 echoes Bṛhadāraṇyaka 1.3.28: "nāsato vidyate bhāvo" (the unreal has no being) is the operational sūtra of "asato mā sad gamaya." The mahā-vākya "ahaṁ brahmāsmi" finds its completion in BG 18.66 where Krishna says "ahaṁ tvā sarva-pāpebhyo mokṣayiṣyāmi" — He who IS Brahman now promises liberation.
