How can one avoid distractions in prayer? If one abides in the presence of God. Indeed, when in the presence of one's judge and one's master, and speaking with him, one does not let one's eyes wander elsewhere. How much more should the one who approaches the Lord never turn away the eye of his heart, but fix it on Him who searches the reins and the heart.
When we return to prayer after a period of reading we find a rejuvenated and invigorated soul, stirred by the desire for God. The best form of prayer is one that implants the clearest idea of God in the soul and thus makes space for the presence of God within us. We become a temple of God when our continuous meditation on Him is not constantly interrupted by ordinary worries, and the spirit is not disturbed by unexpected emotions. Thus, in flight from all things, the spirit who loves God can approach God who drives out everything that leads us to evil, and holds steadfastly to everything that leads to virtue.
And when you pray, see that you ask not for what is alien to your life, and provoke the Lord. Ask not for money, not for human glory, nor power, nor for any of the things that pass away. But seek for the kingdom of God, and all that is needed for your body will be provided; as the Lord Himself has said: Seek ye the kingdom of God, and his justice, and all these things will be added unto you (Matthew 6:33).
