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

Of creations I am the beginning, the end and also the middle, Arjuna. Among kinds of knowledge I am the knowledge of the self, and of those who debate, I am reasoned discussion.

Earlier in the chapter Krishna called himself the beginning, middle and end of beings; now he says the same of whole creations, the cycles in which worlds come forth. Among all branches of learning he is adhyātma-vidyā, the knowledge concerning the self, which the Gita treats as the highest study. Among those who argue he is vāda, discussion aimed at finding the truth, as distinct from debate meant only to win or to tear down an opponent. The verse quietly describes the dialogue itself: an inquiry into the self, carried on by honest question and answer.
