Is there an expression or word for emotional/spiritual arrival?

I am looking for an elegant expression, or better a word, to describe emotional arrival, to be settled down spiritually, to have come home in a sense that you know what you want, you are at peace with yourself, that kind of thing.

I'm a German native speaker, and in German this would be 'angekommen sein' (direct translation: 'to have been arrived')

Is there a quick and elegant way to say this?

Solution 1:

How about come into one's own? From The Free Dictionary:

come into one's own: to become independent; to be recognized as independent and capable, usually after much effort or time.
