Sati • Yonisomanasikara Dearest friends, seeking to clarify my fragmentary understanding of these matters, I would very much appreciate your comments on the distinction between Sati Mindfulness and Yonisomanasikara Attention by way of the Matrix.

Warmhearted, grateful thanks for you taking the time to offer some help.
