This Mental State of the Particle may be described as a state of "_Emotional Excitement_." Let us pause a moment to consider the meaning of these words--it often helps us to understand a subject, if we examine the real meaning of the words defining it. "Emotion" is derived from the Latin word _Emotum_, meaning "to shake; to stir up"--the Latin word being made up of two other words, _i.e._, _E_, meaning "out"; and Motum, "to move." "Emotion" is defined as "a moving or excitement of the mind." "Excitement" is derived from the Latin word _Excitare_, meaning "to move out"--the English word being defined as "a calling to Activity; state of Active feeling; aroused Activity." So you see that the idea of _Active Motion_, and _Aroused Activity_, of Mind, permeates the term "Emotional Excitement," that is used by the writer in connection with the Mental State causing vibration of the Particles of Substance. The single word, "Excitement," will be used by the writer, hereafter, in the above connection, in order to avoid complex terms. To those who still object to the use of a mental term in reference to motion of Substance, he might remark that Science makes use of the term--"Excite," and "Excitement"--in reference to Electrical phenomena, so that he is not altogether without support in the use of the word. Now to return again to our body of Substance--the Sun--the Particles of which are manifesting a great degree of "Excitement," evidencing in Vibrations producing the phenomenon of Radiant Energy. The excitement is shared equally by its Particles, the "contagion" having spread among them. Even the Particles of its atmosphere are vibrating with Excitement, and evidencing Radiant Energy. The Sun is in direct Mental Connection with the Earth (as we shall see presently) and the Excitement is transmitted by Thought-Transference (along this Mental Connection) in the shape of Dynamic Thought-waves of Excitement. These waves have a rate of speed of 184,000 miles per second--why this particular rate, or any rate at all, is not apparent; it being very evident, however, that this particular kind of Mental Action--Excitement, or Thought--is not transmitted _instantaneously_ as is the Mental Quality known as Desire, resulting in Attraction, or Gravitation, which seems to be rather a Basic quality, rather than a temporary disturbance or emotional excitement. But the writer must not get ahead of his story.
