So is there “Good” and “Evil” as opposites? Does one exclude the other?
That would be nice, wouldn’t it? Then one could practically categorize everything and pack it into drawers.
“The light wins against the darkness” and similar.

From a higher perspective, however, one eventually realizes that they are just poles on an axis. And recognizing this axis means overcoming duality.
Birth and death are the same: expressions (poles) of the axis “transient beauty”. For without transience, there is no beauty. Without winter, no spring.
Hot and cold are poles of the axis “temperature”.
Fast and slow define the dimension of “speed”, thus traversing time & space.
Quiet and loud means: There is music, sound, frequencies perceivable by one of our senses.
Bright and dark for the eyes.
Tasty and McDonald’s for the mouth… 😊

Recognize the axis and recognize its potential.
That may be the mysterious “Third Door”…
