The tree of life, the axis mundi is the central point, the pole around which all revolves. The central point of the world is the point where stillness and movement are together. Movement is time, but stillness is eternity. Realizing how this moment of your life is actually a moment of eternity, and experiencing the eternal aspect of what you are doing in the temporal experience -- this is the mythological experience.
It was said that God once sought advice from a Master. "I want to play a game of hide-and-seek with humankind. I've asked the angels what the best place would be. Some said in the depth of the ocean. Others said the top of the highest mountain. Still others, the far side of the moon or a distant star. What do you suggest?"
Said the Master, "Hide in the human heart. That's the last place they will think of!"
