Committing yourself to “contemplation in action” or, rather, becoming a “contemplative in action” is a challenging undertaking and, like all things related to the Divine, depends far more on God’s love and grace than it does on any decision or action I might make. Eastern traditions talk about “mindfulness” and it is a valuable concept, but I think the “contemplative in action” is more concerned with “Godfulness.”
There is, of course, a tension in the phrase “contemplation in action” for our normal view of contemplatives is that they sit stock still, (the perfect Mary as opposed to the imperfect Martha), while all around them daily life surges forth. What Ignatius of Loyola meant by the phrase, I believe, is that contemplatives in action are as recollected and prayerful as any monks or enclosed nuns but are, at the same time, actively involved in the world around them. When my life is held in God’s hands and I am in an intimate relationship with Christ, I am capable of approaching all of reality from a contemplative’s perspective, no matter how many things I have to work on during the day.
When I am in harmony with the Lord, I start to see the world as God’s wondrous creation and I am given the gift of finding God in all things and in all things to find God. Action for action’s sake is mere busyness and prayer, (of whatever kind), divorced from the realities of God’s creation is, at best, imperfect.
