@Icon,
What i spirituality?
I would say something that can only be defined (if at all), only for ones self through one's own experiences, influences, inner chemical and physiological inner workings, relationships, etc.
Perhaps the next time you talk to your friend, maybe try to and ask that person to examine his or her own experiences. The moments that "made their life", good or bad.
The intense-est (did i just make that up? and if so, why isn't it a real word XD ?), feelings, experiences. Although perhaps as Icon said, it is created. Or maybe some spirituality is "false", or subjective.
Regardless, if one feels it (whatever that may be, perhaps diff for every individual, experience it, then to that individual it is "Reality" it is being experienced, in his or her scope of awareness, then so be it. I feel that spirituality is a totally subjective matter, however at the same time, can have many shared elements to the concept.
This is all really rushed, sorry.
Take care,
Peace and Love
Namaste
