'When two hearts unite, they can break even mountains." As two fuse in love, the more does intuition grow, the more does one understand whether the other is happy, or pleased, or displeased, whatever distance may separate them. This is nothing but just the unity of the one person with the other. It is clairvoyance. The mother knows the condition of her son at the battle front. She can see him in her dreams. Hearts which are united in love perceive the state of mind of the loved ones. They do not have to study mysticism or concentration, for they have natural concentration. The mother does not pretend to meditate; love teaches her more meditation than a person who pretends to study it can attain. One cannot, however, hold an object in mind when the heart has nothing to do with the object. Pebbles are not made to eat, and therefore one cannot eat them. The mind is never so satisfied with either an object or a being which it does not desire; therefore it is no use to concentrate specially on what the heart does not desire. The heart which does desire needs no special concentration.
