Feeling nostalgic

I noticed that in many books mindfulness is described as an opposite of being disconnected from the present moment and being lost in thoughts about the past or the future. More specifically, what is meant there is ruminating on regrets about the past or worrying about the future. I am wondering, though, whether reminiscence about the past is necessary a negative thing. For example, mentally reliving a happy memory could potentially be a nice stress relief, if nothing else. There is also a potential argument for regrets in general sometimes serving as a useful learning tool.

But I wonder if a positive case could be made for something in between these two kinds of past-dwelling. For example, considering that the definition of nostalgia is “sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations,” I think that feeling nostalgic implies feeling happy and sad at the same time. I also wonder if then, by definition, every person has something to feel nostalgic about . After all, most people probably have something with happy personal associations that is now in the past.

What do I feel nostalgic about? I certainly don’t leave with the constant feeling of nostalgia, but if I dig for it, it would probably have to be the time when I practiced kendo, or, even earlier, aikido. I miss the sense of awe of participating in something so deeply rooted in a foreign and fascinating tradition and of being aware of the formative effect of the practice on my life.

These are the kinds of thoughts I am having when present moment awareness proves elusive.
