The Most Important Benefit of Mindfulness?

There is a lot of talk about “mindfulness” and its benefits. One benefit that I appreciate and haven’t seen given a lot of air time:
Awareness of and friendly attention to my own inner experience at any given moment protects me from being drawn into the feelings, moods and states of other people, which (by default) I am likely to desirously FUSE with or aggressively REJECT.
With awareness to inner experience, space opens up – space for me and space for him.
Perhaps this is the kind, compassionate, attentive space where “loving your fellow as yourself” is actually possible.
