Being a Mīmāṃsaka and believing in God might be hard

To my knowledge, Veṅkaṭanātha’s Seśvaramīmāṃsā has been commented upon only once in Sanskrit, namely in the 20th c. by Abhinavadeśika Vīrarāghavācārya.
At times, the Sūkṣmārthaṭīkā‘s author seems to disagree with Veṅkaṭanātha insofar as he stresses that a certain position by the Mīmāṃsā school is “not accepted by us” (i.e., by the Viśiṣṭādvaita Vedāntins). Many such cases pertain to the core teachings about language and the Veda being fix according to Mīmāṃsā and depending on God according to Viśiṣṭādvaita Vedānta. In the commentary on SM ad PMS 1.1.29, the Sūkṣmārthaṭīkā is quite explicit:

By contrast, we do not accept the inference said by Mīmāṃsakas, namely ”Each recitation of the Veda has been preceded by one’s teacher’s teaching one the recitation of the Veda, because it is a Vedic recitation, like the present ones”. We do not accept it, because there is an exception, since the probans is absent in the recitation performed by Brahmā of the [Vedic text] based on the Lord (who was Brahmā’s inner controller, so that Brahmā did not need to learn the Veda from a teacher) as well as in the present recitation of the Veda, when it is performed by an ascetic who has made it present (and therefore can see it without the need of a teacher).
And we also do not accept the syllogism because it contradicts the sacred texts speaking of creation and dissolution [of the entire world].

vedādhyayanaṃ sarvaṃ gurvadhyapanapūrvakam adhyayanatvād ity anumānaṃ tu mīmāṃsakoktaṃ necchāmaḥ. īśvaramūlacaturmukhakartṛkādhyayane sākṣātkāritapasvikārite ādyādhyayane ca sādhyābhāvāt vyabhicārāt (ad SM ad 1.1.29, 1971 edition p. 128).

It is easy to see how a Mīmāṃsaka could not have agreed less with Vīrarāghavācārya’s arguments. Mīmāṃsā authors in general believe in a beginningless time and think that the idea of creations and dissolutions is only an unwarranted assumption. Even more dangerous is the idea that an ascetic might see directly the Veda, since this could open the door to yogipratyakṣa and to autonomous religious experiences.

In all the above ways, the Sūkṣmārthaṭīkā‘s author also indirectly points out the gigantic effort Veṅkaṭanātha undertook, almost seven centuries before, when he tried to propose a synthesis of Pūrva Mīmāṃsā and Vedānta.

Philosophical commentaries in ancient India (UPDATED)

Commentaries can be manifold in ancient India. They have different purposes and form, but they all share some characters:

  • they have a given text as their main interlocutor/they are mainly about a given text
  • like with Origene’s commentaries, they are a genre in its own right, not a minor specialisation for authors at their beginnings (Sakai 2015, section 4, suggests that authors in fact needed to have already become acknowledged authorities before being entrusted with the honour of composing a commentary on an influential text.)
  • they are characterised by a varied but strong degree of textual reuse
  • they allow for significant degrees of innovation (This is evident in the case of the Navya Nyāya commentaries on the NS. Outside the precinct of philosophy, juridical commentaries often reflect the recent juridical developments much more than the original text they are commenting upon.)

What is a commentary? UPDATED

And how the Nyāyamañjarī and the Seśvaramīmāṃsā do (not) fit the definition

What makes a text a “commentary”? The question is naif enough to allow for a complicated answer. First of all, let me note the obvious: There is not a single word for “commentary” in Sanskrit, where one needs to distinguish between bhāṣyas, vārttikas, ṭippanīs, etc., often bearing poetical names, evoking Moons, mirrors and the like.
