Although

Although I teach, I am the cap of fools;
Although I love all souls, a fiend am I.
I am not strong, yet for the weak I fight;
At will I sell myself and myself I buy.
At every pause my life I contradict.
To me are ever the same all truths and lies.
To me the earthly beings and He are one.
We fly in His Bosom vast, in us He flies.
