In relation to the paragraph below, please see the queries below it:

**In most Buddhist literature I have read (which is not extensive and is mostly in the Theravada approach) there seems to be a consensus that the one who keeps watch, the knower, is not absolute but is still in the realm of mind and inconstancy.  One develops the mind, the watcher, or the knower in order to reach nibbana which lies beyond.

Please use some synonyms which give some clarity on what is meant by absolute.

Please clarify if there is some other temporary or permanent reality which is present besides the knower and the mind in the last sentence. This would help because otherwise one is puzzled as to there being a watcher and then something or someone else which keep tab of what occurs.

These are common synonyms of absolute, and there are others:

universal

fixed

independent

nonrelative

nonvariable

absolutist

rigid

established

set

settled

definite

decided

irrevocable

unalterable

unquestionable

authoritative

incontrovertible
