What is the meaning of cross bars on the mount of Moon?

These are indications of a worrying nature, always looking for and expecting danger: it gives the saddest side of an active imagination which would be otherwise harmless;  if the Heart line is good in combination with these cross lines on the Moon's mount, the worries are for loved ones, or for affection's sake; if the mount of Jupiter is rayed the worry comes from disappointed ambition; if Mercury's mount is rayed the worry is caused by great anxiety on business matters; but if Mars mount be full and clear it counteracts this worry because of the coolness it indicates in time of trouble. Square fingers lessen the tendency to worry, and a strong thumb enables the subject to overcome the difficulty a great deal.
