St. Paisios Velichkovsky on the Jesus Prayer

Christ is risen! Truly He is risen!

The Jesus Prayer is a work common to the angels and to men. With this prayer, men quickly approach the life of the Angels.

The Prayer is the source of all good deeds and virtues, and drives far away from man the dark passions. In a short time, it makes man worthy to obtain the grace of the Holy Spirit. Obtain it, and before you die, you will obtain an angelic soul. The Prayer is divine rejoicing.

There is no other spiritual weapon that can so efficiently hinder the demons. It burns them like fire burns the brush.

Christ is risen from the dead, by death, trampling down upon death, and to those in the tombs, He has granted life! Truly the Lord is risen!
