How can we conclude that something is unarisen and eternal? Let us suppose there is something (i.e. nirvana) unarisen and eternal.

How can we conclude and trust that it is indeed unarisen and eternal ? Because in order to find out whether it is unarisen, we will have to go into its infinite past; and to find out whether it is eternal, we will have to go into its infinite future.

Nirvana is said to unarisen and eternal.

So my question is : How do we know something is unarisen and eternal ?
Imagine, for example, that you're trying to travel to Paris (or to Rome, or Varanasi, or anywhere else).

So, you ask people, "How to get to Paris?" -- and you follow road signs, which say, "This way to Paris."

When you get to Paris, after you arrive, I don't think you ask yourself, "How do I know this is Paris?"

I think that descriptions of nirvana (like "unarisen") should be understood as instructions or directions like this.



I don't know, maybe another analogy is like, you go with someone to the sea-shore, and they say, "That ocean is always there." You look, and what you see are waves which appear and disappear, and so it's difficult to see what's constant, to see that there is anything that's constantly there.
