Why should we pray? Paul the Apostle said once, "Be consistent in praying," and Jesus said, "Be alert and pray." The prayer is of threefold nature. It is equal to breathing. One should pray so that the soul to breathe and perceive things. The prayer is needful for the soul. It is the contemplation of the highest feelings. Through the prayer we see that a child is praying. It is an appeal and is as needful for the soul as breathing is. Humans need air much more than food. It is proven that a human may stay without air for 25 minutes at most and if we equalize the air with the prayer, which is food for the soul, we see that it is of great significance to it.
