I'm so glad you're doing better ((((((((((sanityseeker))))))))))) It's great that you got a good night's sleep and that you've been able to resist ruminating today (that's huge!)
So glad you had a good day (((((((((lavie)))))))))))) and I hope you're having a relaxing evening. If freezing rain is predicted where you are, it's good to know you are safely at home
Usually I meditate lying down on the floor with my knees bent, feet on the floor, arms at my sides. This is because it's the most comfortable position for me. However, I really like the idea of a more formal meditation practice where you sit upright, with a pose that's erect and dignified, yet relaxed. I did buy a meditation cushion a while back, along with a couple of those yoga bricks to support my knees. But I just can't get comfortable sitting like that for any length of time. So now I just sit in a chair. The last couple of mornings I've sat in a chair for the morning session and I've stuck with the lying on the floor for the evening session. The sitting in the chair feels more like "real" meditation so I'm definitely going to stick with that. The lying on the floor feels more like a relaxation exercise, which is good too!
May you be free of harm and suffering
