Chapter 4: Jñāna Karma Sannyāsa Yoga – Renunciation of Actions through Enlightenment: Conclusion
ओं तत्सदिति श्रीमद्भगवद्गीतासूपनिषत्सु ब्रह्मविद्यायां योगशास्त्रे श्रीकृष्णार्जुनसंवादे ज्ञानकर्मसन्न्यासयोगो नाम चतुर्थोऽध्याय:।
oṃ tat-sad-iti śrīmad-bhagavad-gītāsūpaniṣatsu brahma-vidyāyāṃ yoga-śāstre śrīkṛṣṇārjuna-saṃvāde jñāna-karma-sannyāsa-yogo nāma caturtho’dhyāya:
Om – the symbol of Brahman, tat – that singular Reality (Brahman), sat – the ever abiding presence (Brahman).
Thus ends the fourth chapter entitled Jñāna-karma-sannyāsa Yoga, during the Srikrishna-Arjuna dialogue in Śrīmad Bhagavad Gita, constituting Yoga-śāstra, which falls within Brahmavidya as presented in the Vedic Upanishads.
