Beyond life and death, supra life and death...
Life and knowledge are analogous, but they don't have to be
one and the same. As such, you can know things without being alive or dead. There are an eternity of variations of life and lives. All of which you have lived and shall live.
There are also an eternity of things that don't have anything to do with life or death as "we" know it (and don't know it presently) but yet
these supra-life-deaths can still be known and experienced. Indeed, they are known and experienced, and just because you don't know and experience them in what "we" call the present, doesn't mean
you haven't or won't know and experience them. But you can't live
through or die through them because they're beyond life and death.
Would you like me to describe a supra-life-death experience?
Not an option. Just think about that for a second and you'll see
why it's not an option to explain what such an experience
or knowledge system is--it would be part of life, which is what
you're presently experiencing. To some extent.
