how many nayas are there? what are they?

In Jain philosophy, naya means a partial or particular standpoint used to understand reality.

Commonly, there are 7 nayas:

1. Naigama naya — generic / purposive standpoint
2. Sangraha naya — general or collective standpoint
3. Vyavahara naya — practical or transactional standpoint
4. Rjusutra naya — momentary or present-state standpoint
5. Shabda naya — verbal standpoint
6. Samabhirudha naya — etymological / special-word standpoint
7. Evambhuta naya — exact-meaning standpoint

In some Jain texts, 7 are grouped as 3 main divisions:

• Nischaya-related / deeper view
• Vyavahara / practical view
• Shabda-based finer distinctions

Simple meaning:

A naya shows one angle of truth, not the whole truth. Jainism teaches that reality is complex, so it should be understood through multiple standpoints.

If you want, I can also give the meaning of each naya in very simple language.
