Color in the Visible and Invisible World 287 



With regard to the ether (Jfkdsha) which per- 

 vades all space, science has at last come to this 

 very rational conclusion, as Robert Kennedy Dun- 

 can puts it : " How much we ourselves are matter 

 and how much ether is, in these days, a very moot 

 question " ( The New Knowledge) . Science has 

 discovered also that absolute immobility rest 

 is non-existent; that every particle, every atom of 

 the most solid-seeming matter is in an incessant 

 quiver, and that the velocity of the motion is con- 

 stantly changing. Is not this corroboration of the 

 Tattvic Law, which alone can explain the phenom- 

 enon? 



Think not that these details are a digression 

 from our subject. They are, on the contrary, in- 

 timately connected therewith; for it is most impor- 

 tant as a preparation for understanding the sub- 

 tle sheaths of the body that the reader's imagina- 

 tion be wonted to faring forth into this marvellous 

 world of the infinitesimally small, a clear conception 

 of which is so much more difficult to form than of 

 the vastness of the Universe.
