In the beginning, there is struggle and a lot of work for those who come near to God. But after that, there is indescribable joy. It is just like building a fire: at first it's smoky and your eyes water, but later you get the desired result. Thus we ought to light the divine fire in ourselves with tears and effort.
Though you pray to God every hour, though you have such faith that you can move mountains, even though you give away all of your belongings to the needy, and give your body to be burned, - if you do not practice forgiveness and do not wish to forgive your enemy, then all is in vain, for in such circumstances neither prayer, nor faith, nor charity, will save you, in short, nothing will save you.
Rivalry over material possessions has made us forget the counsel of the Lord, who urged us to take no thought for earthly things, but to seek only the kingdom of heaven (cf. Matt. 6:33).
Go, sell all that belongs to you and give it to the poor and taking up the cross, deny yourself; in this way you will be able to pray without distraction.
Therefore silence, prayer, obedience; when you practice these virtues with the help of God, then you will know the light of Christ is within your soul.
Do not let the sun go down on the anger of your brother (Eph. 4:26); that is, let no one be angry and enraged against his brother until the setting of the sun.
Do not pray that things may be according to your desires, for they are not always in keeping with the will of God. Better pray as you were taught, saying: ‘Thy will be done’ on me (Matt. vi 10). And ask thus about all things, for He always desires what is good and profitable for your soul, whereas you do not always seek it.
If something pushes you to criticism about some business or other of a brother or of a monastery, you, rather, try to pray about the matter, without passing it under judgment of your reason.
The Law (as it is written in the Scriptures) was given to us by Angels and, both before and after the days of the Law, Angels guided our illustrious forefathers to God, either by declaring to them what they should do and leading them from error and an evil life to the straight path of truth, or by making known to them the Divine Law, or in the manner of interpreters, by showing to them holy Hierarchies, or secret visions of super-mundane Mysteries, or certain divine prophecies. Now if anyone should say that God has shown Himself without intermediary to certain holy men, let him know beyond doubt, from the most Holy Scriptures, that no man has ever seen, nor shall see, the hidden Being of God; but God has shown himself, according to revelations which are fitting to God, to His faithful servants in holy visions adapted to the nature of the seer.
Put aside bodily considerations when you stand in prayer, lest the bite of a flea, a gnat or a fly deprive you of the greatest gain afforded by prayer.
