Bhagavad Gita 10.32

10.32 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 all creations I am the beginning and the end and also the middle, O Arjuna. Of all sciences I am the spiritual science of the self, and among logicians I am the conclusive truth.
