Verse 2.127

Sanskrit text and transliteration:

कृत्स्नोपनिषदर्थस्य सूत्रमित्यभ्यधात्पुरा ।
सङ्क्षेपतस्तदर्थश्च सम्यङ्मन्त्रेण वर्णितः ॥ १२७ ॥

kṛtsnopaniṣadarthasya sūtramityabhyadhātpurā |
saṅkṣepatastadarthaśca samyaṅmantreṇa varṇitaḥ || 127 ||

English translation of verse 2.127:

It was stated earlier that the text (“The knower of Brahman attains the Supreme”) is a statement in brief of the purport of the entire Upaniṣad. And its meaning has been well-explained in a concise manner by the mantra portion (which follows it).

Notes:

The text, “The knower of Brahman attains the Supreme,” which occurs in the Brāhmaṇa portion, states aphoristically the central teaching of the Brahmavallī and the Bhṛguvallī. It speaks about (1) Brahman, (2) the knowledge of Brahman, and (3) the fruit which accrues to one who knows Brahman. Since it is necessary to know the nature of each one of them, the Mantra portion, which follows this text, beginning from satyam jñānam anantam brahma and ending with brahmaṇā vipaścitā serves as a brief commentary thereon. It first of all sets forth the nature of Brahman as real, knowledge, and infinite. Secondly, it says that one must know Brahman as identical with the inward Self. Finally, it declares that the knower of Brahman, remaining identical with the Self of all, enjoys bliss which is illimitable and unsurpassable.
