Does anyone know whether there are on-line or CD-ROM English translations of the following available? Ramanuja's "Shri-Bhashya," Shamkara's "Brahmasutra-Bhashya," Nagarjuna's "Madhyamika-Karika," and Vasubandhu's "Twenty Verses" and "Thirty Verses"? If so, can you instruct me as to how to obtain them? Thank you.
