Elder Anthony of Optina

“Your spirit should not grow weary, but should become warm from spiritual reading, from thoughts about eternity, and from prayer, even though it may be brief. Say to the Lord; ‘Gather my scattered mind, O Lord and humble my hardened heart with fear  of Thee, and have mercy on me!’ For without Divine help we are powerless; we cannot even deal with flies, much less invisible enemies.”

– St. Anthony of Optina
