Dear brother!
After three weeks, I once again send you all my warm brotherly greetings. … Brother Augustin's letter brought me great joy, especially with the clear atmosphere of faith that breathes from it. Occasionally, please convey my heartfelt thanks to him and also a request that he does not forget me at the Mother of God of Svatohostýn. There is a solid point in the world that nothing shakes, even when everything around trembles. …
The more fragmented external unity becomes, the more letters and prayers must be created and maintained to uphold internal unity.
(Adolf Kajpr SJ /1902–1959/, letters to a fellow brother; Dachau, summer 1944)
