This mode of thinking is echoed in some Stoicism books I've read. Both "Meditations", and "A guide to the good life" include similar entries.
I really enjoy seeing the parallels between western(?) Meditation/mindfulness practice, and Stoicism. I do believe the meditation we predominantly practice in the west is at least slightly different from the more traditional eastern Buddhist meditation practice. But I do believe that is to be expected, the cultures are fairly different so the adaptation process was bound to create some offshoots.
There was a submission a while ago[0] that I believe does a great job of summarizing some of the cultural changes that meditation practice went through in the west, and how it contrasts to the more traditional eastern practice.
