No better therapy. Or form of prayer exists. I'm a poet, so I'm partial to poetry, of course. IF you're interested, respond and I'll look up the Medium link that shows how to single space lines for poetry - again, if you'd like that option. It took me MONTHS to realize!
Re your poem, I love how you weave light throughout it. From light of life fading and falling stars to stars still shining to enlightenment.
