Meaning, Spiritual but not Religious.
People who believe in a higher power but not participating in any form of organized religion. A typical SBNR picks different things from multiple Spiritual Paths and Religions and mixes it together.
John: "Hey mary in what religion do you believe in?"
Mary: "I dont believe in any religion. I take the parts i like from other religions but dont follow just one Doctrine"
John: "Oh u mean a SBNR?"
