I guess you're asking about what-/who-ever "takes" or "goes to" or
"(re)appears/arises" for/in refuge or any next life or moment? During
life, the whole psycho-physical process/activities rolls along; at death,
excepting arahats, only the psycho. The "soul" thingy could be "ye kesi"
and "maanusa" and a bunch of case & tense changes:
''Ye kesi Buddha.m sarana.m gataase,
Na te gamissanti apaayabhuumi.
As to how we're to interpret that or any other thread(s), I guess it's to
the best of our understanding, taking the whole framework into
consideration, remembering things that set it apart from other teachings,
say, anatta and contemplation of foulness that only Buddhas point out.
