Answer

In Jain philosophical language, Vyāpya (व्याप्य) and Vyāpaka (व्यापक) describe a relationship of pervasion.

• Vyāpya means: that which is pervaded, contained, or always accompanied by something else.
• Vyāpaka means: that which pervades, covers, or is invariably present with the vyāpya.

Explanation

A simple example:

• Smoke is vyāpya.
• Fire is vyāpaka.

Why?

Because wherever there is smoke, there must be fire. So smoke is dependent on fire for its existence in that example. Fire is the broader condition that pervades smoke.

So:

• Smoke is pervaded by fire → Vyāpya
• Fire pervades smoke → Vyāpaka

Spiritual Understanding

In Jain logic and philosophy, this relationship helps in proper reasoning and understanding reality correctly. It is used to understand how one thing is necessarily connected with another, without making false assumptions.

Takeaway

Vyāpya = the pervaded / dependent term
Vyāpaka = the pervading / wider term

In short: Vyāpya is included within Vyāpaka.
