Evolution (I mean Darwin's theory, not the spiritual kind) works by selecting the members of a species best suited to their situation. They
live longer. They breed more. They get away from tigers better. Whatever.
The species changes in response to the reality of death. Without any planning of who they want to be, each species focuses on death, according to how it's most likely to appear for them, in order to avoid it.
Each species ends up being whatever it is. No planning to their bodies, behaviors, and minds. Each feature is a response to something in their
evolutionary history. It helped them survive. Right at the time it appeared. "In the moment", so to speak.
It happens because the priority is avoiding death.
When the priority is really being in one's life; LIVING in each moment, without negative thoughts or feelings, the same thing happens. If the person avoids anything that feels like it goes against that the way a gazelle avoids a leopard or a brush fire.
In time, that individual is going to become a different person.
If they believe that there is an absolute limit on the process, like:
Enlightenment
Oneness with God
Complete purity
Liberation
Being guaranteed a place in heaven
Unconditional love
Final Realization
....or anything like these, the person will no longer have any notion about what to do to continue the process once they reach their goal. Or rather,
that it can be continued at all. And far worse, failure to reach enlightenment becomes a kind of personal failure. Worst of all, other people's failure to try to reach it makes them seem a bit .... coarse.
When an enlightened one teaches their process as 'the way', they fail to see that their state might not be as fulfilling for others. One 'enlightenment' is about love because the PERSON is about love. Another one is about 'being here now' because the person is about that.
Darwinian evolution uses navigation by dead reckoning, away from death. Each species developing in its own direction.
"The Process", if I can call it that, does the same thing.
A species that's really improving its ability to live isn't trying to arrive at a 'perfect' form.
