As a man whose head is under water cannot inhale pure air, so a man whose thoughts are plunged into the cares of this world cannot absorb the sensations of that new world.
One of the fathers used to say that some old men were sitting one day and talking of what was useful to the soul. One of them had the gift of vision, and he saw angels who were waving branches in honor of the old men, but when one of them began to speak of irrelevant things the angels withdrew, and some pigs walked amongst the old men bringing a bad smell and messing up everything. As soon as they began once again to speak of what was useful to the soul, the angels returned to do them honor.

Hold to patience in your hearts, my friends, and put it into action when the situation calls for it. Don't let any abusive word from your neighbor stir up hatred in you, and don't allow any loss of things that pass away to upset you. If you are steadfast in fearing the loss of those things that last forever, you will never take seriously the loss of those that pass away; if you keep your eyes fixed on the glory of our eternal recompense, you will not resent a temporal injury. You must bear with those who oppose you, but also love those you fear with. Seek an eternal reward in return for your temporal losses.

But if you give a strong body rest and ease and idleness, all the passions dwelling in the soul are intensified. Then, even if the soul has a great desire for good, even the very thought of the good that is desired will be taken from you.
Having withdrawn from the palace to the solitary life, Abba Arsenius prayed and heard a voice saying to him, 'Arsenius, flee, be silent, pray always, for these are the source of sinlessness.'
When I wish to open my mouth and to speak on the exalted theme of humility, I am filled with dread, like someone who is aware that he is about to discourse with his own imperfect words concerning God.
