At some stage, the story and details you share to describe who you are no longer resonate. The drama, entertainment value and emotional triggers lose their appeal. You do nothing and watch elements of the identity you construct fall away of their own accord. The urge to offer credentials or opinions fades. Listening replaces talking.
In essence, you systematically see through layers of your self-created illusions. You recognize reasons for attachment and detachment, and outgrow certain ways of experiencing the world. You begin to realize it is part of life to feel and let go of all perceptions, not only those that evoke negativity, but also those that trigger positive and uplifing feelings. Perceptions of lows and highs are all transitions guiding you home. What is natural unfolds through it all. The mind has selective awareness. The heart always knows what is meaningful. As heart and mind are seen as one, be that.
"Renunciation is not getting rid of the things of this world, but accepting that they pass away." -Aitken Roshi
