When have you been the most at peace?

There have been a few times when I've felt really peaceful. I remember a few of them happening when I was on a run. Where I live there's this park that ends at the shoreline of a bay, so I sit there and catch my breath for a bit mid-run.
It's total stillness there, and there's very few people who are around the area, so it's amazingly quiet. In the summer I take my shoes off and put my feet in the water. There's these tiny grayish fish that start to float near me after a few minutes. If I stand long enough, they swim right over my feet in little darting movements, resting every so often right on top of my foot. It's such a strange feeling, but mindblowing when I really think into it- how often do average people get to connect with nature like this? It gives me an immense sense of peace and calm, knowing that these tiny creatures trust my presence enough to rest on me.
