This Is Life!: Revolutions Around the Cruciform Axis

Fr. Seraphim (Rose) of Platina
"We are told by the Holy Fathers that we are supposed to see in everything something for our salvation. If you can do this, you can be saved."
Father Seraphim Rose: His Life and Works

St. Herman of Alaska
"The true Christian is a warrior making his way through the regiments of the invisible enemy to his heavenly homeland."

Fr. Seraphim (Rose) of Platina
"Anyone who is attracted merely by glittering censors, incense and beautiful vestments, he, first of all, will fall down before Antichrist."
"Signs of the End Times"

Fr. Seraphim (Rose) of Platina
"When I became Christian I voluntarily crucified my mind, and all the crosses that I bear have only been a source of joy for me. I have lost nothing, and gained everything."
Father Seraphim Rose: His Life and Works

Fr. Seraphim (Rose) of Platina
"Do not trust your mind too much; thinking must be refined by suffering, or it will not stand the test of these cruel times."
Letters from Father Seraphim

St. Theophan the Recluse
Here is a rule for reading:
Before reading you should empty your soul of everything.
Arouse the desire to know about what is being read.
Turn prayerfully to God.
Follow what you are reading with attention and place everything in your open heart.
If something did not reach the heart, stay with it until it reaches.
You should of course read quite slowly.
Stop reading when the soul no longer wants to nourish itself with reading. That means it is full. If the soul finds one passage utterly stunning, stop there and read no more.
The best time for reading the Word of God is in the morning. Lives of saints after the mid-day meal, and Holy Fathers before going to sleep. Thus you can take up a little bit each day.
