Some parts are translated really well, some parts you misunderstood.

Here is what I'd change:
"and blew my mind a thousand times."

"As I had scaled the mountain,
taken on the sea, storm, and snow"

"What a sight I saw!"
Also, I think that's too free; I'd make it to:
"I was impetuously met by a gaze,
it raptly carried me away"

"And I looked into his wild eyes."

"Die Zeit wich dem Moment – wie alles Flehen"
means
"Time gave way to the moment – just like all pleading did"
That's difficult to understand, I'll reword it:
"Time left [very poetic way to say that it stood still] to make room for that one moment - and time did so in the same way as all pleading did [= all cravings disappeared, too]"

"He, who journeys not avidly"
I'm not sure about what that's supposed to mean.

"Nicht Besitz noch Mammons Fesseln,
keinem Führer, keinem Helden,
nur sich selbst den Fron gegeben,"
is complicated. It means
"He has provided his drudgery
to neither possessions nor to the chains of Mammon[=money],
nor to any leader or hero,
but only to himself"
It's a bit strange in German, though, since it should be "die Fron", not "den Fron", and is worded quite strangely.

"Die Gunst, zu erleben,
nach nichts zu streben,"
means
"The blessing to experience
striving for nothing"
