To me, on a very fundamental level, the distinction between 'Bushcraft' and 'Religion' is not as obvious and clear cut as one may first believe.
For most indigenous peoples and indeed our ancestors the two went hand in hand. (Reading many of the posts on this topic for some, they still do.)
Bushcraft was and still is, simply a way of living, of getting by, making life comfortable and getting the most from the resources available. Since the dawn of time, this is what it was all about.
In order to influence, aid and guide us in life, many religions and belief systems developed. Why? To help build and develop the above definition of 'Bushcraft' ie. being alive. Existing and making the most in this world, the next and the previous, or whatever context was deemed appropriate.
I think that these days our views on what denotes 'religion' are somewhat guided by the developments of the last few thousand years, many of these beliefs are being questioned by society as a whole these days. Our search for alternatives often leaves us looking for 'something' similiar to what we know about and understand.
In many ways this is making the most of what is available and trying to put it into context with our modern lifestyles.
As 'bushcrafters' though we have a distinctive advantage over everybody else, in that often we are 'out there' living (albeit relatively brief) primitive lives. We sit around the fire, forage from the land, wake up on cold frosty mornings, watch wildlife or view rainbows. In essence 'we are alive'.
The feelings and emotions we experience when out in the woods, especially when we sit alone for a time, are the very emotions and feelings that we as humans have felt since it all began.
I believe its all about getting back to basics and interpretting this in which ever way you choose, that allows you to feel alive!!!!!! Whether that be through believing in One God or many, or just looking at life on a spiritual level.
I am not trying to promote or denounce any form of religion or belief system, just to try and put an extra edge on Primitive living.
