Two separate points are getting mixed here:

1. “Dinosaurs” word not in Jain scriptures
2. Kevalgyān (omniscience) meaning “knows everything”

Let’s separate them.

---

1. Why “dinosaurs” are not mentioned?

• The word “dinosaur” is a modern scientific term (19th century).
• Jain Āgams and śāstras were spoken/written thousands of years before this word existed.
• Jain texts do not list every species by modern names.

They classify living beings more broadly:

- 4 gati: dev, manuṣya, tiryañc, nāraki - Within tiryañc: many types of animals, reptiles, birds, insects, etc.

From Jain view, dinosaurs are simply one type of tiryañc jīv (animal/reptile category). So they are included in the category, even if the English name “dinosaur” is not written.

Just like:

• Āgams don’t say “tiger” in English, but talk about vyāghra, siṃha, etc.
• They don’t say “bacteria” with modern scientific detail, but they clearly speak of sūkṣma jīv, nigod, etc.

Scripture language is descriptive and categorical, not a modern biology textbook.

2. Then what does Kevalgyān “knows everything” mean?

Traditional Jain doctrine (both Digambar and Śvetāmbara) is very clear:

• Kevalgyān = anant, purna, sarvākārak jñān

Infinite, complete knowledge.

• It knows:

- All dravya (all substances) - All paryāya (all their modes/changes) - Of past, present, and future – all at once, without mistake.

So from Jain standpoint:

• A Kevalī definitely knows:

- The existence, form, time-period, and karmic relations of beings we now call dinosaurs - And of countless other beings and things that humans haven’t discovered at all.

But:

• What the Kevalī knows and
• What finally comes into scripture (Āgam / granth)

are not the same thing.

3. Why is it not written in scriptures then, if Kevalī knows it?

Because:

1. Deshnā (teaching) is given according to the listener’s capacity

- Tīrthaṅkars speak Divya-dhvani, which is perfect. - But what gets understood, remembered, and written down by gaṇadhars, Āchāryas, and later scholars is limited. - They record what is useful for spiritual liberation, not a full biological catalogue.

1. Āgam is for moksha-mārga, not science syllabus

- Main aim: explain ātma, karma, bondage, liberation, right conduct. - Details of every species, geological period, etc. are not necessary for moksha, so they are not exhaustively listed.

1. Time and language limitations

- Scriptures are in Prakrit / Sanskrit, and for people of that time. - They use examples and terms known to that society; not future scientific words.

So no mention of the word “dinosaur” does not mean:

• Kevalgyān is incomplete, or
• Jainism “did not know” such beings exist.

It only means:

• Scriptures did not choose to name and describe them in our later scientific style.

---

4. Does this reduce Kevalgyān?

In classical Jain darshan, no.

• Kevalgyān remains sarvajña – knows all.
• Āgam is true but not total duplication of Kevalgyān; it is the part that is expressed for guiding souls.

In simple words:

> Kevalgyān knows dinosaurs. > Our scriptures don’t use the modern word “dinosaur”, > because they were never meant to be a modern science book.
