And make him master of the world of sense
Whence he will be allowed to liberate
Powers he can put to use for his own ends.
So have I tried, as far as in me lay,
To make fresh progress in the healing art.
This toil endeared me to the brotherhood.
Its members made me free of their estates
To seek to find the forces that reside
In plants and ’neath the surface of the ground,
That they may yield for us new benefits.
