One thing is that Buddhist and traditional Zen Teachings have much "praying to" as well, for perhaps the vast majority of Buddhist and Zen Buddhist folks. Praying to Amida Buddha, Kannon, Shakyamuni, Taira, you name it. It must be hard wired into us, and is not different in any substantial way from praying to Jesus or Mary.
Even the statues are said to be "brought to life" in Zen temples in Japan in a special ceremony turning them into, if you will, "telephones" to the Buddhas and Bodhisattvas. That is not my interpretation, by the way (I am more a "everything, every leaf and stone, is a telephone to Buddha, and Buddha is the phone too" kind of fellow). (This is a Korean temple, but they do a similar ceremony at Zen temples in Japan. Yes, the rope represents being connected by the "telephone line." )

I have not done such a Ceremony at Treeleaf. The leaves and stones and wooden statues and you and me are already as live as they could ever be.
Now, if you really get into the higher "theology" of all this, "outside power" is inside, "inside power" is outside, and Amida and company are just "symbols" and embodiments of something. What that "symbol" represents and embodiment encompasses, well, I leave that for you to taste on your Zafu sitting cushion.
