Captain ZEN RA the RECLINED

Riddle 1: 

No wheels, no wings, but I still make a ride,
I vanish in moments, but open the mind.
Shared in a circle, my journey is brief—
Yet legends are born in my silent relief.

Who am I?

Riddle 2:

I rule from stillness, I drift, not race,

Others chase stars—I chill in place.

With one eye closed, I see much more,

Tell me: what’s the name of my core?
