Greetings Indologists, 

I am looking for two PDFs -- one article and one book. Please see below...

Horstmann, Monika. “The Emergence of the Nāthyogī Order in the Light of Vernacular Sources.” International Journal of Tantric Studies 10, no. 1 (2014).

I found a URL for Horstmann's article ( http://asiatica.org/ijts/10-1/emergence-nathyogi-order-light-vernacular-sources ), but the PayPal links on the page seem to be broken and I cannot access the full article. WorldCat requests through my library have gone unanswered.

Kiehnle, Catharina. Songs on Yoga: Texts and Teachings of the Mahārāṣṭrian Nāths: Jñāndev Studies I and II. Stuttgart: Steiner, 1997.

I already own a hard copy of Kiehnle’s two-volume set back in the USA, but I am currently conducting research in Nepal and international shipping costs are too expensive. If anyone has scanned a soft copy I would be greatly appreciative. NOTE: At present, I only need a PDF of the first volume (ie. Songs on Yoga), not the second volume.  

Thank you.
