Rāhu, the Filter and the Smṛti Passage
During a solar eclipse visible over Pune, a study circle of thirty students watches through certified filters and notes that the calculated time of first contact matches observation to the minute. A guest pandit reads a smṛti passage stating that a demon, Rāhu, seizes the sun, and says the text cannot err, so the students' eyes must be wrong. A Nyāya student objects that perception and verbal testimony cannot both stand here and asks which pramāṇa decides. A Vedānta teacher replies that the passage is arthavāda - eulogistic praise - and was never meant as astronomy. A second student protests that this is convenient: if a text is set aside whenever it clashes with science, no testimony is ever reliable. The teacher asks for a short written resolution that respects both the text and the observation.
1. Classify each claim in the dispute by the pramāṇa that would support it, and identify where the disagreement actually lies.

The students' observation is pratyakṣa - direct perception, here aided by an instrument and by calculation. The calculation is anumāna (inference) from astronomy, and its exact match with observation is what makes the perceptual claim strong.
The pandit's claim about Rāhu rests on śabda - verbal testimony, specifically a smṛti text. Note that it is not perception (no one perceives a demon) and not inference (no observed mark is offered).
The teacher's claim that the passage is arthavāda is a claim about the text's genre, and it is established by interpretation - the same śabda, read in context with the surrounding passage and its purpose. This is where the dispute really lies: not between perception and testimony, but between two readings of what the testimony is for.
The second student's objection is itself a claim about reliable testimony and needs its own justification - it is a general epistemic principle, not an observation.
So the disagreement is not 'eyes versus scripture'. It is a disagreement about the scope and intent of a text, which is why quoting it louder cannot settle anything.
2. Using Nyāya's account of valid testimony, resolve the conflict. Then answer the second student's objection.

Conditions for valid śabda: the speaker must be āpta - trustworthy and knowledgeable on the matter at hand - and the sentence must be well-formed and unambiguous. Where a text speaks outside its competence, its testimony does not generate knowledge, just as a reliable doctor's opinion on metallurgy carries no weight.
Applying this: on the question 'what is happening to the sun at 9:14 a.m.?', the competent sources are observation and calculation. The smṛti passage, read as a narrative of Rāhu, is not offering an account of the mechanism; the teacher's arthavāda reading is therefore not an evasion but a claim about the text's subject-matter. On matters of dharma and mokṣa the same text is within its competence and its testimony stands.
Answering the second student: the objection confuses rejecting a text with limiting its scope. Nothing is discarded; a claim is being assigned to the domain where it can be true. Testimony remains indispensable - no one verifies the date of the eclipse's prediction from scratch, and we accept the calculation itself on the authority of astronomers. Second, the check is principled, not opportunistic: the criterion is competence-in-domain, applied in advance, not 'whatever clashes with today's science'. If the students' observation were later overturned, the text would not be retroactively vindicated as astronomy.
3. What does the Advaita distinction between vyāvahārika and pāramārthika explain here - and where would using it be a misuse?
Read the worked answer
What it explains: the eclipse belongs to vyāvahārika, the transactional order of experienced things, causes and predictions. Its reality is not denied, it is located. Rāhu as a mythological agent and the eclipse as an astronomical event can be spoken of at different levels without one cancelling the other, much as a rope mistaken for a snake is genuinely rope and only apparently snake. The distinction supports the teacher's reading: the passage's concern is the transience and delusion of the phenomenal order, not the orbital mechanics of that order.
Where it would be misused:
- As a silencing move. If any clash is dismissed with 'that is only vyāvahārika', the distinction becomes unfalsifiable and no empirical claim can ever be corrected. Misuse begins when the distinction is invoked after the contradiction appears, rather than as an independent reading of the text.
- To deny the eclipse. Saying the eclipse is 'unreal' and therefore nothing to plan for is a misuse: at the transactional level it is real, and eye damage is real.
- As a substitute for evidence. The distinction cannot tell us whether the north well is contaminated or what the text's genre is; those need observation and interpretation.
Used well, the distinction ranks orders of discourse; used badly, it exempts a claim from every test.
