being aware of how slim the chances for the success of my query actually are, I, nevertheless, would like to ask, if anyone of you may have a digital copy of this book:

or, in fact, of any other edition of the text known under various names as prayogamukha-[maṇḍala/ maṇḍana], prayogasaṃgraha, vārarucasaṃgraha, kārakacakra etc.

thank you very much in advance, 

Andrey Klebanov
