"When the period of warfare comes, we are overwhelmed by thoughts and cares of all sorts. This is when we must turn to the Lord in our hearts and keep silence. If we cannot abandon the thought that is bothering us immediately then we must keep silence. We should not think about anything. It is not ours to think. The Lord knows what we can take and what we cannot. Then, when we are in silence and our mind is quiet, we should give it something to do so that it will not wander. We should pray. Let the mind pray from the heart. Thus, gradually we will become accustomed to prayer, and prayer will become a habit to us, just like any task that we learn to perform. Pray in this manner, without words, and when the Lord sees our endeavors, when He sees that we seek Him and wish to be with Him in all eternity, then He will give us strength, and the heart then will dwell in constant prayer. Then we will do our work while listening to the prayer in us."
- Elder Thaddeus of Vitovnica from Our Thoughts Determine our Lives
