Yazirian Bonzai tree practice

Thinking about yazirian religious practices and the fan created one tree. The belief in the one tree in the after life pre dates Fo1 going back 1000s of years. A place of religious worship would have been a particular species of tree forced to grow, in much the same manner as a Bonzai tree, to conform to a religious ideal. Fo1 naturally doesn't like religious practices it can't control so its limited access to viable specimens of this tree.
