The life and teaching of Zarathushtra give an example to those who tread the spiritual path of the manner in which to begin the spiritual journey. Zarathushtra is said to have been born from the huma tree. The interpretation of this idea is that the Spirit of Guidance does not come direct from heaven; he is born from the human family and the tree is the family. It has been a great error of some religious people that out of devotion to their master they placed him, through their imagination, on a pedestal where they themselves could not ever prove him to be through reasoning. It can only stand on the horizon of faith. No doubt faith is the foundation and the lamp which lights the path, but reason is the globe over it which makes its light appear.
