Dale Carnegie(New Format) description

There is a strange sensation often experienced in the presence of an audience. It may proceed from the gaze of the many eyes that turn upon the speaker, especially if he permits himself to steadily return that gaze. Most speakers have been conscious of this in a nameless thrill, a real something, pervading the atmosphere, tangible, evanescent, indescribable. All writers have borne testimony to the power of a speaker's eye in impressing an audience. This influence which we are now considering is the reverse of that picture--the power their eyes may exert upon him, especially before he begins to speak: after the inward fires of oratory are fanned into flame the eyes of the audience lose all terror.
