There is a meditation tradition that advises that we have
a mind "like a mirror". The idea is to simply be aware
and let incoming sensations, be they physical, mental
or emotional, reflect off of you like it would off of a mirror.
No ingesting, masticating, digesting, or regurgitating. Sit
comfortably (even if standing or walking) and let the universe
present what it will. This non-reactive "mirror" attitude
produces a tension-less clarity whose undistracted focus
allows for a pure attention undiminished by judgments,
comparisons or inner chattering. This is when you segue
from concentration to meditation to contemplation and
transcend the attachment and identification to body and
mind and the suffering that this delusion always inflicts.
This may be worth reflecting on, but possibly not
beneficial to think about.
