On the devotional side, Krishna Das also continues to move me in massive way:
But that's only two examples, both musicians have a great wealth of beautiful and incredible work. I'm not a person who separates religious from secular music either.
This particular song is one that very much captures my 'word-view' quite strongly: "Laugh, love, live, learn"
I must be a mantra person, since I like the Krishna Das piece but I'm not enamoured with Christian hymns, or sermons.
