Ditto in support of the “active” meditation ideas.
I stopped wearing earbuds when I went on long bike rides… as the local military base that allows cyclists bans them.
It was the best thing that ever happened to me.
Once I got used to it, I got more “flow state” rides that felt like meditation.
I also find playing poker meditative and relaxing.
I don’t play a lot of hands, so I use my teime trying to calculate odds and predict hands.
It is the same idea at those meditative adult coloring books.
