Is it possible to pray while we are working? On the surface it seems that this will distract us from our work. The reality is that it will enhance our concentration and our ability to do quality work unhindered by distractions and anxiety.
Elder Paisios says,
When someone is doing work that needs concentration, i.e. he is driving a car, or he is operating on a patient, he should also say the Jesus prayer so God can help him and enlighten him; however, he should pray with his heart, and use his mind to concentrate on his work and thus avoid doing any mistakes.
Prayer can help us concentrate and gain greater insight into our work.
The Elder says,
The more the mind concentrates on praying, and is being humbled, the more it is enlightened by the grace of God. However, the more it gets dispersed and confused due to its haughtiness, the more it becomes troubled; therefore the our mind, which is clean by nature, fills up with dirty thoughts.
It is through prayer that we act with a “clean” mind. Without prayer we are left with our own often confused thoughts. We play over and over in our minds negative thoughts about this or that person. We play over again and again scenarios about what might befall us in the future. With continuous prayer our mind become still, clean from distracting thoughts, only filled with God and the work that is in front of us as this moment. We are held in the vision of His will for us.
