Man’s contact with the outer world is such that there is a continual mechanical interchange going on; every moment of his life he is partaking of all that his senses allow him to receive. Therefore very often the man who is looking for faults in others, who is looking for evil, even though he may not be a wicked person, is yet partaking unknowingly of all that is evil. Once deceived, a person is always on the look-out; even with someone who is honest he will look for deceit, as he holds that impression within himself. Thus a hunter who, comes from the forest where he has just received a blow from a lion, will shrink even from the caress of his mother; and when we consider how many impressions, agreeable and disagreeable, we receive from morning till evening, we realize how someone may become wicked without meaning to.
For in point of fact. Although the body belongs to the earth, yet the soul belongs to God, and from above man has received nothing but goodness. With the wickedest person in the world, when one can touch the deepest depths of his being one finds nothing but goodness there. So if there is any such thing as wickedness or badness, it is only what man has acquired; and he has not acquired it willingly but simply because he is open to all impressions, as it is natural for every man to be open to impressions.
