Not-liked experiences include aging, sickness, physical pain, boredom, stress caused by demanding work, and emotional pain like anxiety, anger, disappointment, and depression.
And they are unavoidable.
Attitude
“... the last of the human freedoms—to choose one's attitude in any given set of circumstances ...”
- Victor Frankle
However, with the right attitude, these pains become "messengers" that inform our work on the path to optimal wellness, like Prince Siddhartha's encounter with old age, sickness, death, and a yogi set him off on the path to Buddhahood.
Accepting the Not-Liked
The most difficult part of that work is accepting the things we don't like.
With a wise attitude, we stop identifying with the pain and the one experiencing it. Instead, we identify with awareness and accept whatever we experience as a continuously changing stream of phenomena.
