Grief work is essential to the adult psyche
I just finished a three day weekend grief ceremony and been practicing grief as a thing this past year.
Obviously there's the failure case where you can get stuck in a loop around your trauma and grief. But, the opposite failure case also exists that most people are repressing their feelings and thereby getting stuck in their head. I'd argue a lot of the transhumanist folks are in this camp.
But an actual ceremony where everyone is supported, witnessed, and held in their grief and rage is a beautiful thing. In my experience, there's a certain half-life to each wave of grief and coming out of it, I'm more capable of taking in joy and being resourced. To the extent, a person can actually inhabit great grief seems to be correlated strongly to how much they can inhabit great joy and power with integrity. There isn't so much of a shadow of the psyche being terrified of meeting pains it cannot deal with and subtly using power to avoid them or fill them.
Seems like a huge missing piece in culture between all the yoga, fitness, authentic relating, and what not. To actually turn towards the broken places and let the body grieve. Many of the times, the grief isn't even about a lost loved one but just grieving the Earth, grieving old disappointments, grieving the suffering of loved ones, grieving ancient wounds that might not even be mine.
