Everyone receives an impression on seeing a certain person or looking at a certain situation. One may not believe that impression, but all the same it is there. The first impression tells a man whether he will be successful or not, whether a person is right or not, whether there will be friendship between two people or not. And when this faculty is developed, a person can get an impression of a place and of persons and of conditions. Impressions come to those whose mind is still; those whose mind is active cannot take impressions. For the mind is like water: when the pool of water is disturbed, one cannot see any reflection in it.
