Saint Theophan the Recluse
There
are two ways to prepare ourselves to be in communion with God. One is
through ascetic struggles and the other is the contemplative way, turing
the mind to God--Saint Gregory of Sinai says, "God is gained either by
activity and work, or by the art of invoking the Name of Jesus." He
tells us that the first way is longer and the second is quicker and more
effective...
It
follows from this that we should from the very first give full
instructions on the practice of the Jesus Prayer to everyone who repents
or begins to seek the Lord ...because it is in this way that one can
most quickly become steadfast and spiritually aware, and achieve inner
peace....
The practice of the prayer is called an "art", and it is very simple...
There
are deviations from the right way of praying; therefore we must learn
it from someone who knows all about it. Mistakes occur chiefly from the
attention being in the head and not in the heart.
He who keeps his attention in the heart is safe.
Safer still is he who at all times clings to God in contrition, and prays to be delivered from illusion.
