Each time I have encountered an obstacle in my life, each time I have been deprived of some happiness—some apparent happiness—a consolation has come immediately to dispel my psychological pain. For something tells me: “All that happens is done for your own good and is done by the Divine Grace.” Is it good, is it healthy to think like this?
Not only is it right, good and healthy to think like this, but it is an absolutely indispensable attitude if one wants to advance on the spiritual path. As a matter of fact, it is the first step without which one cannot advance at all. That is why I always say: “Whatever you do, do the best you can, and leave the result to the Lord; then your heart will be at peace.”
