Of creations, of bringings-forth, I am the beginning and the end and the middle too; I am the arising, the continuance and the dissolution, O Arjuna. At the opening it was said that I am the beginning and the end of beings, of those that have a soul lodged in them; here, however, the distinction is that I am so of every creation, of the mere fact of creation. Of sciences I am the science of the Self, since it has liberation for its purpose and so is the chief. Of those who dispute I am disputation, since it is the cause of settling the truth of a matter and so is the chief; and so I am that. By way of the disputant, of the kinds of speaking, disputation, wrangling and cavil, it is disputation that is taken here by the word 'of those who dispute'.
