This is a great phrase Mingyur Rinpoche uses often that I find to be an extremely helpful reminder. There is a middle ground between giving up and fixating on a result, which is action without tightly grasping. Putting in effort toward a desired end, seeing what comes of it, adapting and changing course as we learn what works and what doesn’t.
Do not give up. But let it go. Letting go is not giving up.
Try our best to make an effort, use our capacity, skills, resources, but at the same time don’t hold too tightly to the result. Accepting whatever happens without giving up.
Accepting sometimes there is no solution, without giving up.
Inner strength or resilience to learn and grow from obstacles, which may become opportunities later.
Like compost: dead flowers become potential for new growth later. If we get fixed on one idea that doesn’t pan out, this excludes infinite other possibilities. Impermanence is more alive and colorful than fixed mind.1
