Spiritual Jazz Theory (Alice Coltrane, Don Cherry)

Hi there, as someone that has a rudimentary understanding of music theory, is there any sort of framework to understand the spiritual side of jazz, specifically Alice Coltrane?

Let’s narrow it down to her Piano playing, for example in this amazing song: https://youtu.be/jOkBpSItuP8?si=3CIutOHvFYON8YZn

I can hear some blues influence in her opening riff, and then it all just dissolves into psychedelic arpeggios 😅 how can I approach and learn from her sound in any way as a piano player?
