I believe that works that touch the Divine or teach us or are still with us centuries after their creation are the ones that did not come out of a place of power or control or techniques, but came at the moment when the heart let go and God answered the question.
Gratitude is the most fruitful way of deepening your consciousness that you are not an "accident", but a divine choice. It is important to realize how often we have had chances to be grateful and not have used them. When someone is kind to us, when an event turns out well, when a problem is solved, a relationship restored, a wound healed, these are very concrete reasons to offer thanks.
What fascinates me so much is that every time we decide to be grateful, it will be easier to see new things to be grateful for. Gratitude begets gratitude, just as love begets love.
