Hmm in that case secular spirituality would make sense, kind of?!
I´m pretty sure that there is a definition of spirituality as a way of thinking or in contact with higher self? I suppose that person would say i live on spiritual principles and they would come from....where?
I guess someone that really understands buddhism and is following that path would describe themselves as then living on a spiritual path...
It is an interesting thread especially the bit about chakra balancing underwear lol
