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.
When selfishness vanishes, all you want from life is to give. It is a constant source of joy. Not that you are blind to sorrow. Personal suffering is gone, but for that very reason there is no barrier separating you from the suffering of others. And that immense empathy releases intense action. "What one takes in by contemplation," Eckhart says, "one pours out in love." You live to give, to alleviate the sorrow and improve the lives of those around you, and in that giving is more joy than the world knows. It is the perfect fusion of the inward and outward currents of life, of meditation and action.
