I FINALLY managed to locate this particular gem.
Then I decided to add (IMHO) the best version of The Saundaryalahari (V.K.Subramanian) that I could find.
And I absolutely had to add the invaluable Encyclopedia of Sacred Sexuality by Rufus Camphausen for its unique entries pertaining to matters cognate.
Corollary : If you are familiar with Kenneth Grant's particular interest in the 15 Nitya Devis (or Kalas) of the Goddess, this is the source material.
Further translations/commentaries of both works available upon request.
Any etymological/artistic insights gained are best explored privately with a bottle of Dassai and a VPN.
