Bhagavad Gita Chapter 10, Verse 32
सर्गाणामादिरन्तश्च मध्यं चैवाहमर्जुन | अध्यात्मविद्या विद्यानां वादः प्रवदतामहम् ||
sargāṇām ādir antaś ca madhyaṁ caivāham arjuna adhyātma-vidyā vidyānāṁ vādaḥ pravadatām aham
Among creations, I am the beginning, the end, and the middle, O Arjuna. Among sciences, I am the knowledge of the Self; and among debates, I am the logical conclusion.
Krishna reveals His presence in the structure of creation, knowledge, and reasoning. 'Sargāṇām ādir antaś ca madhyaṁ caivāham arjuna'—among creations, I am the beginning, the end, and the middle, O Arjuna. Krishna is not just present in creation—He IS the beginning, middle, and end. 'Adhyātma-vidyā vidyānām'—among sciences, I am the knowledge of the Self. Self-knowledge (adhyātma-vidyā) is the highest knowledge. 'Vādaḥ pravadatām aham'—among debates, I am the logical conclusion. The logical conclusion is what resolves all arguments. This verse shows Krishna as the structure of creation (beginning, middle, end), the highest knowledge (Self-knowledge), and the resolution of all debates (logical conclusion).
