The writer asks you to remember, particularly, that while the Desire-waves of the Particles,--and their Thought-waves of Excitement--are changeable, disconnected, and inconstant; the Line of Gravitation is never broken, and could not be unless the Particle of Substance was swept out of existence, in which case the balance of the Universe would be overturned, and chaos would result. The Divine Plan is perfect to the finest detail--every Particle is needed--is known--is counted--and used in the Plan. And Gravitation is the plainest evidence of the REALITY of The Infinite that is afforded us. _In it we see the actual machinery of The Infinite._ No wonder that great thinkers have bowed their heads reverently before its Power and Awfulness, when their minds have finally grasped its import. Verily the sparrow's fall is noted, and known, as the Biblical writer has recorded, for the fall is in obedience to that great Law that holds the Particles in their places--that makes possible the whirl of worlds, and the existence of Solar Systems--that, indeed, makes possible the Forms of Life as we know them--that Something that forever and ever has, and will, silently, ceaselessly, untiringly, and without emotion, fulfilled its work and destiny--GRAVITATION. * * * * * The Theory of Dynamic Thought also holds that in addition to the existence of the Cosmic Mind, or Ocean of Mind-principle--and the Lines of Attraction that run through it, each particle has its Mental Atmosphere, or Aura. The Aura is an Atmosphere of Mind that surrounds the Particle--and also the larger bodies--and also living forms higher in the scale. This Aura is merely an extension of the bit of Mind that is segregated or apparently separated from the Cosmic Mind, for use by the individual Particle, Mass, or Creature. Through, and by means of this Aura the Particle takes cognizance of the approach and nature of the other Particles in its vicinity. The same rule holds good in the case of the Creatures, including Man, as we shall see in a later chapter. The fact is mentioned here, merely in order to connect the several manifestation of Mental Phenomena mentioned in the several parts of this book. * * * * *
