I see this type of reading as facing death. What the charnel grounds meditation did for people with that option, the literature on death does that for the cerebral readers of the west. The Denial of Death has been a seminal text for me, and I wish not to defensively avert my gaze, but to see it as the larger tapestry of impermanence, conditioned coproduction. Our world is sanitized. It's hard to get close to death. There are no charnel grounds to go meditate at.
When Smartt used the phrase "word salad", it was to disparage the concept as someone who doesn't understand. She reports the metaphors of dying can elude us, but can make sense often.
Reading this book I wrote relatives and asked about last words in the family. I thought about what I'd like my ending to be like. Taking a look at it, I decided some CDs I want to listen to: Bud Powell, Grant Green, Lester Young, Billie Holliday, La Traviata, La Bohem, Hydrogen Jukebox and Satyagraha. The books I want read to me. I'd like the satipatthana sutta read to me, the diamond sutra and other perfection of wisdom texts, the precious garland, the bodhicaryavatara, songs of Milarepa, the Lotus Sutra, the sutra of the golden light, the lankavatara sutra and the pure land sutras, a survey of Buddhism.
Sangharakshita wrote about the 6 element practice, which he learned from Yogi Chen, and how it's another way to look at dismantling, seeing that there is no essential self. Sangharakshita suggests you only really do that one on retreat, in an environment where deep practice is supported. I kept doing it after one retreat because I had a white light experience, and I started to feel like I was dying. That's the whole point, a spiritual death, to be reborn, but it calls for supportive conditions and the workaday life is not supportive. I do it a few times when I build up my practice, but I also let it fall down to rebuild again. Or rather it falls down despite my best efforts at vigilance. You can listen to a version of the meditation on the Insight Timer, lead by Bodhipoksa. Here is the free buddhist audio search. Do this practice within the community, don't do it without connecting to a tradition of your own choosing.
Then there is volunteering at a Hospice, like Norman Fisher discusses in one of his essays. I'm considering that.
May you be happy, may you be well.
