Mustard is for sudden depression which descends out of the blue and lifts just as suddenly for no apparent reason. This gloom can be very severe; it is like the descent of a cold dark fog, overcasting everything and destroying normal cheerfulness. The sufferer is completely taken over by gloom and
unable to shake it off at will.
The positive potential of Mustard is the return of joy, supported by an inner stability and peace which cannot be shaken or destroyed under good circumstances or bad.
