Prayer demands that the mind should be pure of all thought and should admit nothing not belonging to prayer, even if it were good in itself. As if inspired by God the mind should withdraw from all things and hold its converse with Him alone.
He who prays with the lips, but neglects his soul and does not guard his heart, prays to the air and not to God; and he labors in vain, because God attends to the mind and fervor, and not to prolixity. One should pray with all one’s fervor, with one’s soul and mind & heart, with the fear of God, and with all one’s strength.
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.
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.
Be fond of working with your hands, but still more of the memory of prayer; because the first does not always bring us the fruit of that occupation, while the second does so unceasingly. Do not stop praying until you have paid your due of prayer in full, and do not listen to the thought that it is time to sit down to work. Equally, when you sit at work, do not be too concerned in it, lest you agitate the heart by your haste and make it worthless for prayer.
The one who prays ought never to halt his movement of sublime ascent toward God. For just as we should understand the ascent 'from strength to strength' as the progress in the practice of the virtues, 'from glory to glory' (2 Cor. 3:18) as the advance in the spiritual knowledge of contemplation, and the transfer from the letter of sacred writing to its spirit, so in the same way the one who is settled in the place of prayer should lift his mind from human matters and the attention of the soul to more divine realities.
Before the war begins, seek out your ally; before you fall ill, seek out your physician; and before grievous things come upon you, pray, and in the time of your tribulations you will find Him, and He will listen to you.
Fire makes iron impossible to touch, and likewise frequent prayer renders the intellect more forceful in its warfare with the enemy. That is why the demons strive with all their strength to make us slothful in attentiveness to prayer, for they know that prayer is the intellect's invincible weapon against them.
You describe how bitterly you regret the inefficacy of your prayers. Beware: to wish for consolation or revelation in prayer is a sure sign of pride. Pray humbly, in perfect simplicity, seeking salvation only through forgiveness, & having faith that God will extend to you His mercy - as He did to the publican.
Ask the angels and the saints to intercede for you, just as you'd ask people who are alive. Stand face to face with them, in the belief that they are also standing face to face with you.
