<Would you help me to understand the meaning and origin of expression
'ta.m kutettha labbhaa'.>
The syntactical words that compose this phrase are: ta.m + kuto + ettha +
labbhaa. It is not recorded very often in the canon and the question is how
to construe the phrase. It is evidently an idiomatic expression meaning
something like "therefore (ta.m), how (kuto) would it be possible (labbhaa)
in this case (ettha) i.e. the one that has just been defined
(that it does not happen). The expression seems to be a truncated version of
more explicit expressions, like, for instance ta.m kutettha, aananda,
labbhaa, ya.m ta.m jaata.m bhuuta.m sa.nkhata.m
palokadhamma.m, ta.m vata maa palujjiiti neta.m t.haana.m vijjati'.
