De Smet, one of India's great advaitins

George McLean, in an email to me of 7 April 2010 (spellings corrected): 

“What excited me about Fr. De Smet's original work was that it enabled the richness of Shankara and the Hindu tradition of the interior path to the divine to be re-related to the material world from which it has been separated.

Father De Smet pioneered this re-relation by opening the connection which the advaitin scholarship had severed in the interpretation of Shankara.

I see this as the key to the present need not to abandon the sacred but to show it to be the real foundation of the sense of the material life, and hence for us of the scientific world in which we now live.

I saw with my own eyes the excitement this caused at a meeting at the University of Madras when two key people jumped up at the end of his talk, which summarized the first part of his dissertation, to say that this was the way Hindu philosophy needed to be done and that he was one of the greatest advaitins in India, indeed in the whole world.” 

Sayana and Anandagiri

In "Langage et Connaissance de l'Absolu chez Samkara" De Smet casually mentions Sayana's and Anandagiri's sub-commentaries on the Taitt. Up., without giving any further references. I have been able to find the following details:

Tika of Anandagiri on Shankaracharya's Bhashya on the Taittiriya Upanishad

Upanishad-bhashya-sangraha, Mahesanusandhana Samsthanam, Mt. Abu, 1979-1986. Sankara's bhAshyas on the kaTha, mANDUkya, taittirIya, chAndogya and bRhadAraNyaka upanishad, with Anandagiri's TIkAs and other sub-commentaries. See http://www.advaita-vedanta.org/avhp/biblio.html

Sayanacharya's Bhasya (part of commentary on the entire Taittiriya Aranyaka)

Taittiriya Aranyaka, with Sayana Bhashya . Anandashram, Pune 1926. See http://en.wikipedia.org/wiki/Aranyaka

A. Mahadeva Sastri. Taittiriya Upanishad: with the commentaries of Sankaracharya, Suresvaracharya, and Sayana (Vidyaranya), pp. 80 (free download at: http://www.archive.org/download/taittiriyaupanis00sankiala/taittiriyaupanis00sankiala.pdf)

The commentarial tradition of Advaita

Editing De Smet's articles, I am learning so much. The commentators of Sankara, for example. Francis X. Clooney (Theology after Vedanta, Albany: SUNY Press, 1993, 17-18) provides the following list, which is useful even if not exhaustive:

Vacapati Misra (mid 9th C) - Bhamati.
Amalananda (13th C) - Vedantakalpataru (commentary on the Bhamati)
Appaya Diksita (16th C) - Kalpataruparimala (commentary on the Vedantakalpataru)
Anandagiri (13th C) - Nyayanirnaya (commentary on Sankara's Brahma Sutra Bhasya)
Govindananda (end 16th C) - Bhasyaratnaprabha (commentary on Sankara's B.S.Bh., drawing on the Nyayanirnaya)
Prakasatman (13th C) - (Sarirakanyayasamgraha) (a synthesis of issues at stake in the more ample commentaries)
Advaitananda (17th C) - (Brahmavidyabharana) (a direct commentary on Sankara's B.S.Bh.)

In addition, there is:
Dharmaraja Adhvarindra (16th C?) - Vedanta Paribhasa.

The two major schools seem to be:
Vacaspati Misra's Bhamati school
Prakasatman's Vivarana school.
