When we practice it in meditation, self-acceptance entails noticing thoughts and emotions with empathy, but with a reduction of ….. the reactions of approval, disapproval or final judgment. This can give rise to two important realizations. First, through maintaining this equanimity, we can see patterns of thought and behaviour as they come and go – and let them do just that. So this provides a neutral space in which to witness what we often take to be “myself” as a dynamic of impulses, thoughts, responses and fresh impulses….. The second realization that depends on equanimity (and on investigation) is that mind-states are radically impermanent. If through sustaining equanimity, we stay focused on a mind-state, thought or emotion we notice that it ends – not in a sudden stop, but in a fading and an unravelling.

What I find most fascinating is that in truly being with the “negative” emotions without judgement, they don’t simply disappear — but release some repressed energy and leave behind a luminous space of innocence and childlike joy as well…
Working with trauma sufferers, this is key to healing. The hardest symptom is dissociation, leaving this moment to think scary thoughts or avoid all together experiencing this moment.
C-PTSD people have trauma thoughts which switch on the fight or flight or freeze mechanism. So those with activated PTSD actually have a real body release of cortisol, adrenaline, higher BP, respiration and heart rate. Tunnel vision, a loss of fine motor skills also unfolds.
being able to stay present without thought is the way to heal. The delusion of thoughts having power becomes evident.
Everytime we run from fear or uleasantness the more disconnected from this moment we become. it takes daily practice to improve and apply this gift.
Great quote again, Karl.
