Kṣetra–Kṣetrajña-Jñāna–Jñeya-Viveka
Field, Knower, Knowledge, and the Knowable
सर्गाणामादिरन्तश्न मध्यं चैवाहमर्जुन । अध्यात्मविद्या विद्यानां वाद: प्रवदतामहम्
sargāṇām ādir antaś ca madhyaṃ caivāham arjuna | adhyātmavidyā vidyānāṃ vādaḥ pravadatām aham ||
Wahai Arjuna! Dari segala ciptaan, Akulah awalnya, Akulah akhirnya, dan Akulah pula yang berada di tengah. Di antara segala pengetahuan, Akulah pengetahuan tentang Diri (adhyātma-vidyā/brahma-vidyā); dan di antara para pembicara serta pendebat, Akulah vāda—perbincangan tertib yang menuntun pada penetapan kebenaran.

The Supreme identifies Himself as the origin, culmination, and sustaining middle of all created processes, and as the highest form of knowledge—Self-knowledge. He also sanctifies “vāda,” reasoned debate aimed at arriving at truth, presenting ethical discourse as a dharmic tool for discernment rather than victory or humiliation.
Within the battlefield dialogue, Krishna is enumerating His vibhūtis (manifest excellences) to stabilize Arjuna’s understanding and devotion. This verse highlights that the Lord pervades cosmic time (beginning–middle–end) and also guides human pursuits of learning and argument toward right conclusion.
