The law of mortal mind that says our work, whatever it may be, will not amount to anything, must be broken. Watch your own thought that you be not tripped and used as a channel to prevent the good work you are trying to do. This is most important, as the subtlety of evil is to prevent Truth from appearing. Another subtlety is the claim that to ‘handle the serpent’ will not do any good. Look well to this. Mary Baker Eddy (Carpenter,, Jr., Gilbert, 500 Watching Points, #192)
