St. Diadochos of Photiki: The soul will not desire to be separated from the body...

The soul will not desire to be separated from the body unless it becomes indifferent to the very air it breathes. 

All the bodily senses are opposed to faith, for they are concerned with the objects of this present world, while faith is concerned only with the blessings of the life to come. 

Thus one pursuing the spiritual way should never be too greatly preoccupied with beautifully branched or shady trees, pleasantly flowing springs, flowery meadows, fine houses or even visits to his family; neither should he recall any public honors that he happens to have been given. 

He should gratefully be content with bare necessities, regarding this present life as a road passing through an alien land, barren of all worldly attractions. For it is only by concentrating our mind in this way that we can keep to the road that leads back to eternity.'
