Bhagavad Gita

Chapter 8: Akṣara-brahma-yoga: – Comprehending the Imperishable RealityConclusion

ओं तत्सदिति श्रीमद्भगवद्गीतासूपनिषत्सु
ब्रह्मविद्यायां योगशास्त्रे श्रीकृष्णार्जुनसंवादे
अक्षरब्रह्मयोगो नाम अष्टमोऽध्याय:।

oṃ tat-sad-iti
śrīmad-bhagavad-gītāsūpaniṣatsu
brahma-vidyāyāṃ yoga-śāstre
śrīkṛṣṇārjuna-saṃvāde
akṣara-brahma-yogo nāma
aṣṭamo’dhyāya:

Om – the symbol of Brahman, tat – that singular Reality (Brahman), sat – the ever abiding presence (Brahman).

Thus ends the eighth chapter entitled Akṣara-brahma Yoga, during the Srikrishna-Arjuna dialogue in Śrīmad Bhagavad Gita, constituting Yoga-śāstra, which falls within Brahmavidya as presented in the Vedic Upanishads.
