Panic: The Visible and Invisible
In Halacha and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
Genuine religiosity is demanding - it requires a sensitivity to the physical human condition as well as the hidden, divine dimension. Living in a manner that combines the visible and the invisible, and more so, harmonizing the two as equal components of our lives, is a tremendous challenge. It is too easy to make a selection - as many individuals and even religions do - between the visible and invisible, preferring one over the other. However, living the one with an imbalance regarding the other is not what Judaism teaches.
