There is also "Reconciling yogas: Haribhadra's collection of views on yoga"http://books.google.com/books?id=fZ6qQM ... &q&f=false
I have only read the first 2 chapters, so am unable to discuss it in any depth. Haribhadra is a Jain, and he structured his work in line with the structure in Patanjali's Yogasutra. He seems to be especially antagonistic with the emerging Tantric shools. He also advanced arguments again Vedantin and Buddhist yoga. The Buddhist work he used was a text by an individual named Bhadanta Bhaskara, and apparently there are no other record elsewhere in the Buddhist world for this person or his system of Buddhist yoga. Curious indeed.
If you believe certain words, you believe their hidden arguments. When you believe something is right or wrong, true of false, you believe the assumptions in the words which express the arguments. Such assumptions are often full of holes, but remain most precious to the convinced.
