Kisi bhi Tirthankar ka naam paanch jñān (ज्ञान) mein se kisi ek jñān ka naam nahi hai.

Jain dharm ke anusaar 5 prakar ke jñān hote hain:

1. मति ज्ञान (Mati-jñān)
2. श्रुत ज्ञान (Shrut-jñān)
3. अवधि ज्ञान (Avadhi-jñān)
4. मनःपर्यय ज्ञान (Manahparyaya-jñān)
5. केवल ज्ञान (Keval-jñān)

24 ke 24 Tirthankar in jñānon ko prapt karte hain (ant me sabhi ko Keval-jñān hota hai), lekin inmein se kisi jñān ka naam seedhe roop se kisi Tirthankar ka naam nahi hai.
