Looking at some of what have often been thought of as existential dualities:

Loving what is or working to make things better…
Accepting ourselves as we are unconditionally or aspiring to grow and express more of our full potential…
Maximizing intentionality or following the flow of life…
Bettering our individual ego or transcending it…
Free will or determinism…
Being in the now or planning for the future…
Increasing witness consciousness or losing oneself in experience…
Open mindedness or critical thinking…
Persistence or surrender…
Boundaries or allowing…
Being or becoming…
Freedom or structure…
Gratitude or desire…
Rights or responsibilities…
Agency or communion…
Particle or wave descriptions of the quantum…
The fundamentality of subject or object…
All of these, commonly seen as paradoxes to be embraced or extremes to find a middle path between…are indeed orthogonal and equally fundamental partial truths…to be simultaneously optimized…fully reconciled in a congruent understanding of the higher dimensional (eg, more complex) nature of reality.
