Now you also have Brahmanas, which are commentary. Now to be clear, there are verses in the Vedas that can be many of these, that can be Aryanakas and Upanishads. So these things are not mutually exclusive. Now in the Hindu tradition, one of the unifying factors are the Vedas and the subclassifications or subcategorizations of the Vedas. These are often viewed as divine revelations. Even though the Vedas themselves, some of the authors refer to themselves as authors, as people who are introspecting on these ideas and writing about them, it is believed by many Hindus that this is divine revelation. And the term for that is Shruti.
