Well, for one thing, in the tradition of Zen that I’ve practiced, there is no prayerful worship and there is no affirmation of a deity.
Scientists believe that every occurrence, including the affairs of human beings, is due to the laws of nature. Therefore a scientist cannot be inclined to believe that the course of events can be influenced by prayer, that is, by a supernaturally manifested wish. However, we must concede that our actual knowledge of these forces is imperfect, so that in the end the belief in the existence of a final, ultimate spirit rests on a kind of faith. Such belief remains widespread even with the current achievements in science.
Every person has his own ideas of the act of praying for God’s guidance, tolerance, and mercy to fulfill his duties and responsibilities. My own concept of prayer is not as a plea for special favors nor as a quick palliation for wrongs knowingly committed. A prayer, it seems to me, implies a promise as well as a request; at the highest level, prayer not only is a supplication for strength and guidance, but also becomes an affirmation of life and thus a reverent praise of God.
