Speaking as a humble mountain climber in the physical world, there's some interesting things with life-as-mountain or love-as-mountain analogies.
These might be ironic or not:
Mountains have summits, so one must descend or just die there, and statistically most accidents happen on the way down. I'm not sure if this applies to our illusion-mountains, but I expect it does.
Climbing is one of the most efficient motions for a human being, we generate our greatest amount of power when hiking up an incline. Walking down is actually harder on the body. Maybe the greater struggle is descent?
The air at the top is hard to breath on big ones, so hard that if you took a short cut like flying in a helicopter and stepping out, you'd die in 15 minutes. So using this reasoning, in line with other posts, love without strife or struggle is less special. In fact it means one must die, symbolically at least, because no growth or change occurred during the ascent (acclimitization).
No matter how far apart or on what side of the mountain any number of people are when they start climbing, they all end up on a comparitively very small little spot. Imagine how we don't know anyone else who is climbing, what they do for a living, why they're here, we don't even speak the same language, but we all know to head for that little target at the top. And when we get there and see another climber pop up from another side, we don't have to say anything to know what the other is feeling at that moment.
Other than that distraction, which got me thinking about the upcoming season and the climbs I have scheduled, I liked the poem. Quite deep and thought provoking, certainly way way better than the usual poem on this site! It's always gutsy to post a poem. I don't have the nerve myself, only the reactionary critic here!
