The "standard" Śrīvaiṣṇava commentary on the Upaniṣads is by one Raṅgarāmānuja (as I recall, 17th century, but could not confirm it in a brief search). There is an older commentary by Kūranārāyaṇa (who may have been a student of Parāśara Bhaṭṭar, so, close
to Rāmānuja's time) on the Māṇḍukya (and the Māṇḍukya is taken to be both the prose part and the verses otherwise attributed to Gauḍapāda) and, if memory serves right, on the Taittirīya; there is a commentary on the Īśā by Vedāntadeśika (and I believe
by Kūranārāyaṇa too).
Hi,
Rāmānuja never wrote a work that was a commentary on a full Upaniṣad like those of Śaṅkarācārya. Does anyone know of
Upaniṣadic commentaries written in the Viśiṣṭādvaita tradition in either Tamil or Sanskrit? Or published scholarship relating
to same?
Thanks.
