Wherefore a monk's whole attention should thus be fixed on one point, and the rise and circle of all his thoughts be vigorously restricted to it; viz., to the recollection of God, as when a man, who is anxious to raise on high a vault of a round arch, must constantly draw a line round from its exact centre, and in accordance with the sure standard it gives discover by the laws of building all the evenness and roundness required.
John Cassian...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'.

John CassianThe second request of the very pure soul is to see the coming of the Father's kingdom (cf. Mt. 6:10). What this means first of all is that each day Christ should reign among holy men. And this happens when the devil's power has been driven out of our hearts through the expulsion of sinful foulness and when God has begun to reign within us amid the good odors of virtue. With fornication vanquished, chastity rules; with anger overcome, peace is king; with pride under foot, humility is sovereign.
John CassianWhen we say 'hallowed be Your name' to God what we are really saying is 'Father, make us such as deserve knowledge and understanding of how holy You are, or at least let Your holiness shine forth in the spiritual lives we lead.' And this surely happens as men see our good works and glorify our Father in heaven.
