According to YS II 15: [blah blah blah...]...duHkham eva sarvam vivekinaH ...
everything (sarvam) [is] only (eva) duHkha for a vivekin.
duHkha 1 mfn. (according to grammarians properly written %{duS-kha} and said
to be from %{dus} and %{kha} [cf. %{su-kha4}] ; but more probably a
Pra1kritized form for %{duH-stha} q.v.) uneasy , uncomfortable , unpleasant ,
difficult R. Hariv. (compar. %{-tara} MBh. R.) ; n. (ifc. f. %{A}) uneasiness ,
pain , sorrow , trouble , difficulty S3Br. xiv ,
Taimni: To the people who have developed discrimination (viveka) all is
misery...
So, is a vivekin at least in CC?
Is the meaning of viveka approximately the same in yoga and advaita-vedaanta?
