detachment

When I preach, I usually speak of detachment and

 say that a man should be empty of self and all things;

 and secondly, that he should be reconstructed in the simplicity
  beyond all words and beyond all understanding that God is;

 and thirdly, that he should consider the great longing

 which God has set up in the soul, such that by means of it 

man may wonderfully attain to God; and fourthly, 

of the purity of the divine nature.

~ Meister Eckhart
