God this one is hard

Some are so,
Others are that,
Beyond and entry,
In front of exit,
The past exists,
Future unhinged,
Blue in the wave,
Red is the course,
From the east,
Is a west,
South is central,
Ground the north,
Fate an act,
Remorseful duty of destiny,
Left wide closed,
Traffic went right,
Edging away from shadows,
A solution is not,
Yet answer to be seen,
A riddle this is,
Yet not what,
Am I is,
Clouds and birds,
What am I?
