One of the things my wife and I have been watching lately is a documentary series (available on disc through Netflix) titled Mystic Lands.
It was conceived rather ambitiously for a network TV series (originally airing on the Learning Chanel). The idea was a 13 episode series looking at numerous different locations of the world, and the spiritual practices that were (or, in some cases, are) practiced there, without cultural bias or prejudice as to the views of the practices being shown.
We’ve seen 4 episodes so far, and I have to say that I think they succeed. Series director Chip Duncan (who is interviewed about the project in an extra feature on Disc 2) wanted to show spirituality as a potential unifying force of humanity despite the diversity of beliefs, and I respect that view tremendously.
I would choose to phrase it this way: WHAT you practice is not so important as IF that practice means something to you. On the other hand, something being successful as a faith for you is no indicator of it’s rightness for anyone else. You have a right, and obligation, to do what is right for you, but you have no right or authority to enforce it on anyone else.
Ultimately, your decision to make someplace a spiritual place for you is the only thing that is necessary. You can make it spiritual just by setting up an altar in a room in your basement.
