Somewhere after WWII, a man named Lester Levenson had a heart attack, and facing mortality, asked himself some hard questions. He ended up with his own process of coming to terms with reality and finding happiness and peace that came to be known as The Sedona Method (book). The bullet points of the vipassana-like process are:
- Feel what you are feeling
- Ask "Could I let this feeling go," allow this feeling to be here, welcome this feeling
- Ask "Would I be willing to let this feeling go?"
- Ask "When?"
- Repeat as necessary
It's been a while since I was exposed to this. I believe Lester had a thing where he would go beyond the basic feelings and further subdivide things into "wanting approval" or "wanting control". More opportunities for noting/labeling, like submission/dominance or craving/aversion.
Also as I recall, Lester described first a level of happiness where he emphasized dissolving one's need to change things and leaning in the direction of love (perhaps like metta), and then "beyond" that a level of peace where he described letting go of trying to find happiness and giving support to other people.
