In my personal opinion, music is the most powerful artform and all artforms are expressions of love. And literature is an artform. I never ever got into literature like poetry, not an avid reader. But I’ve found allot of power and beauty in some spiritual gitas which are poems. Also some spiritual texts which don’t fit into any format. Maybe prose if that’s correct.
Music is not just the most powerful, it’s by far. How can we measure power.
In literature you would measure it by how much meaning can be communicated per word count. That’s why poetry takes the trophy. Because it’s dense.
I imagine that people who really love poetry, probably read it very very slowly, letting it unfold in full not wanting to skip along. Savoring every line. Because I’ve experienced that myself.
With music the impression or effect it can create in you can be so strong, you may feel you can’t breathe. You may play a tiny bit of something in your own head and savor each note and feel it moving you from the inside out. In my experience no literature comes close to Music.
Just my opinion or experience.
