It seems that the1948 ed. of the Candravākya-s corresponds in fact to the pages 82-86 of the 1948 ed. of the Haricarita by K. Raja (see below the link, or https://archive.org/details/in.ernet.dli.2015.495181 - https://archive.org/details/in.ernet.dli.2015.383340 - https://archive.org/details/HaricaritaByParamesvaraBatta) with some additions (which ones I do not know)

The reference to the Candravākya-s specific volume is found on Jisc and Hathitrust :

Bonjour,

Does someone know if there is somewhere an edition or, at least, some examples from this Vararuci's text.

On the internet, a lot of people talk about it, but no one gives an example of these vakia.

Thank you.
