Most people mistakenly believe that all you have to do to stop working is not work. The inventors of the Sabbath understood that it was a much more complicated undertaking. You cannot downshift casually and easily. This is why the Puritan and Jewish Sabbaths were so exactingly intentional. The rules did not exist to torture the faithful. They were meant to communicate the insight that interrupting the ceaseless round of striving requires a surprisingly strenuous act of will, one that has to be bolstered by habit as well as by social sanction.
I have quitted all forms of devotion and set prayers but those to which my state obliges me. And I make it my business only to persevere in the Holy Presence, wherein I keep myself by a simple attention, and a general fond regard to God, which I may call an actual presence of God; or, to speak better, an habitual, silent, and secret conversation of the soul with God, which often causes me joys and raptures inwardly, and sometimes also outwardly, so great that I am forced to use means to moderate them and prevent their appearance to others.
