"The nature of mental prayer isn't determined by whether or not your mouth is closed. If you understand you are speaking to God then mental and vocal prayer is joined. Remember it is an obligation that we strive to pray with attention. We all know that speaking with God while thinking of a thousand other vanities would amount to nothing less than turning our backs on Him. So the secret is to think of Him as near, not as far away. We can do this even in the midst of our daily tasks."
St. Teresa of Avila
