The closest I've ever gotten to a deep meditative state, a couple of times, was while walking at sunset with music that meant a great deal to me. Nature and music - a perfect combination. I get relaxed walking at sunset without music, but don't achieve that meditative state without it.
What a nice sentiment you and your partner have with sending something like that. I see my husband every morning, but sending a weekly bit of music to represent the theme of life at that time would be a nice addition.
It something that started due to lack of time but evolved into a thing which is fun and meaningful also. Well, to us anyway.
