The Prophet: The Coming of the Ship
(http://www.lojban.org/tiki/tiki-index.php?page=The+Prophet%3A+The+Coming+of+the+Ship&bl):

   as he descended the hill, a sadness came upon him
   mo'i ni'a lo nu badri cu cfari

Question:
How can I distinguish the above use of { mo'i } from that one in { mi
bajra mo'i ti'a le barja}, "I run to the backside of the bar"? Isn't a
terminator like { ku } needed here after that pair of tenses so that a
grammatical room for the elided sumti { le cmana } "the hill" is
preserved instead of being overlapped with { lo nu badri }?

Since this instance of { mo'i ni'a } is directly followed by the sumti
{ lo nu badri } and therefore identical to the structure of { mo'i
ti'a le barja }, I tend to read it as something like "as he went under
the state of sadness, [something unspecified] began".
