Prayer is easy only for beginners and for those who are already Saints. During all the long years in between, it is difficult. Why? Because prayer has the same inner dynamics as love, and love is sweet only in its initial stage, when we first fall in love, and again in its final, mature stage. In between, love is hard work, dogged fidelity, and needs willful commitment beyond what is normally provided by our emotions and our imagination.
It's when I say, "I don't know how to love," and, "I don't know how to pray," that I first begin to understand what love and prayer actually are.
You must have a room, or a certain hour or so a day, where you don't know what was in the newspapers that morning, you don't know who your friends are, you don't know what you owe anybody, you don't know what anybody owes to you. This is a place where you can simply experience and bring forth what you are and what you might be. This is the place of creative incubation. At first you may find that nothing happens there. But if you have a sacred place and use it, something eventually will happen.
