I have subscribed to the Buddhist magazine, Lion's Roar because I enjoy, like and am guided by Buddhist wisdom. Here is a case in point of a very good explanation of how we are affected by duality and what we can do to assuage our suffering.
Here is an article entitled, "The 8 Worldly Concerns" from Lion's Roar's page called "Beginner's Mind" subtitled "Buddhism by the Numbers." Since I do not profit monetarily from this blog, I'm confident Lion's Roar won't mind my sharing their article in it's entirety:
"The eight worldly concerns classify the attachments and aversions that yoke us to samsara, the cycle of suffering. There are four hopes and corresponding four fears, which we cycle through endlessly-until, that is, we discover enlightenment (which includes liberation from the eight worldly concerns). This list is from the Indian philosopher Nagarjuna, with comments by Buddhist teacher Judy Lief:
1. Happiness vs. 2. Suffering
Once we have happiness, fear arises, for we are afraid to lose it. When suffering arises, no amount of wishful thinking makes it go away. The more we hope for it to be otherwise, the more pain we feel.
3. Fame vs. 4. Insignificance
We are obsessed with fame and afraid of our own insignificance. When it dawns on us how hard we need to work to be seen as someone special, our fear of insignificance is only magnified.
5. Praise vs. 6. Blame
We need to be pumped up constantly or we begin to have doubts about our worth. When we are not searching for praise, we are busy trying to cover up our mistakes so we don't get caught.
7. Gain vs. 8. Loss
Just as we are about to congratulate ourselves on our success, the bottom falls out. Over and over, things are hopeful one moment and the next they are not, and in either case we are anxious."
I would encourage you to examine these concerns in yourself and see where you are in the 8 worldly concerns continuum. It is a matter of having a perspective about these dualities we experience and how best to navigate between the extremes with the idea of your final extrication from samsaric duality into the enlightened state of unity consciousness. This is true freedom.
