Bhagavad Gita 10.32

सर्गाणामादिरन्तश्च मध्यं चैवाहमर्जुन।अध्यात्मविद्या विद्यानां वादः प्रवदतामहम्॥

sargāṇāmādirantaśca madhyaṃ caivāhamarjuna |adhyātmavidyā vidyānāṃ vādaḥ pravadatāmaham ||

Among creations I am the beginning, the middle, and the end, O Arjuna; among the sciences, I am the science of the Self; and I am the logic among controversialists.

I am the beginning, the middle, and the end of creation; among sciences, I am the science of spirituality; I am the discussion among disputants.

Our plain-language meaning of this verse is waiting for scholar review.
