Chiggala Sutta

Dear Jim,

I have a little question, I was glad to find the already translated
Chiggala Sutta on the web
<http://www.accesstoinsight.org/canon/samyutta/sn56-048.html>, but
found it strange this version used the words 'sheer coincidence' in
relation with rebirth.  I looked up the Thai version and the
translation was 'after a very long time, it could sometimes happen
(that)'.  I do not know what the original Pali is, perhaps you could
tell us which is closer?

Thank you in advance,

Amara
