The magnetism of the mind is a form of life which is communicated by people. For example, people are in a room and there is a dull person there and everybody feels very dull and all of a sudden a bright person comes in with a lot of wit and in no time everybody feels better. That's the miracle of the magnetism of the mind. It is magnetism, you see. It is something that manifests itself in speech, but it can even manifest itself in the glance of a person. You can see right away those who are quick to pick up things and communicate meaningfulness to another person. There are those who have a kind of electricity in their minds, and just immediately it gives you life again. Whereas the mind itself can be depleted of its energy by boredom. Challenging thoughts will immediately give vitality to the mind.
