Q: Is it possible to have a life free of doubts and fears and what do we need to do or not to do?
A: Life is a succession of events, from which we achieve spiritual maturity. To doubt is only a method of the consciousness that helps us to understand things better, that is to say: The inner and outer reality.
If we have inner doubts, spirituality promises to free us from all those doubts through the real understanding of the meaning of the intrinsic way of life. Which is to live in order to realize Love. And then, doubts and unhappiness are transformed into the virtue of faith and the personal relationship with Love, which means, with God.
This is fundamental and crucial but is not a magic act that assures a life with no problems or difficulties. That is unreal and we have to understand that the human being is always very close to pain and suffering. And this is because of the nature of the mind.
Nevertheless, all those processes will be overcome, when the meaning of life is found, as far as values and morals are referred. This means that we will confront doubts, fears, etc, with enough courage and dedication to process every experience and to give our best.
To conclude: Human life will always be fragile. But when human life and the presence of Love, become one, then, all the common miseries of existence can be overcome. But not by the use of arrogance and power but by the humility of a heart that receives the grace and purity of the true and real God.
