Train yourself to cut off an intrusive thought immediately… Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
Confirm yourself in this truth: that every Divine writing that is in agreement with the path of salvation instructs, teaches, chastises, and strengthens, that our path might be ever according to God.
All men want peace; but they do not know how to attain it. Paissy the Great, having lost his temper, begged the Lord to deliver him from irritability. The Lord appeared to him and said, ‘Paissy, if thou dost not wish to get angry, desire nothing, neither criticize nor hate any man, and thou wilt have no anger,’ Thus every one who renounces his will before God and other people will always be at peace in his soul; but the man who likes to have his own way will never know peace.
It is impossible for the mind to escape disturbing thoughts, but it is possible, for any who take sufficient care, either to admit them or reject them.
In patience is the assembly of all the virtues by which our souls are saved, as St. Ephraim says: having acquired patience, one touches on every virtue; for one rejoices in sorrows, and is well-tried in misfortunes, is joyful in danger, ready for obedience, filled with love, glories in vexation, is humbled in reproaches, unwavering in misfortunes; he who has acquired patience has acquired hope, and such a one is adorned with every good work.
Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
If the soul is vigilant and withdraws from all distraction and abandons its own will, then the spirit of God invades it and it can conceive because it is free to do so.
Keep your mind from malicious thoughts of your neighbors, knowing that such thoughts are hurled by diabolical power, to keep your mind from your own sins and from seeking.
Obedience is necessary not only for monks, but for all people. Even the Lord was obedient. Proud and self-assured do not let grace reside within them, and therefore they never have internal peace, whereas the soul of the obedient easily accepts the grace of the Holy Spirit, bringing with it joy and serenity.
If you will pray for your enemies, peace will come to you; but when you can love your enemies - know that a great measure of the grace of God dwells in you, though I do not say perfect grace as yet, but sufficient for salvation. Whereas if you revile your enemies, it means there is an evil spirit living in you and bringing evil thoughts into your heart, for, in the words of the Lord, out of the heart proceed evil thoughts - or good thoughts.
O man, learn the humility of Christ and the Lord will give you to taste of the sweetness of prayer. And if you would pray cleanly, be humble and temperate, confess yourself thoroughly, and prayer will feel at home in you. Be obedient, submit with a good conscience to those in authority; be content with all things, and your mind will be cleansed of vain thoughts. Remember that the Lord sees you, and be fearful lest you anywise offend your brother, whom neither dispraise nor grieve, even by a look, and the Holy Spirit will love you and will Himself be your help in all things.
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
Where there is pride there cannot be grace, and if we lose grace we also lose both love of God and assurance in prayer. The soul is then tormented by evil thoughts and does not understand that she must humble herself and love her enemies, for there is no other way to please God.
Till the advent of grace man lives his life and thinks that all is well and prosperous with his soul; but when grace visits him and dwells with him he sees himself quite otherwise, and losing grace again he realizes his unhappy state.
