138 Evolution of Life and Form. 



able to trace beyond the limits of his senses into a 

 finer working ; in dealing with our Vayu and 

 A'kasha, he classes them together, and his air is 

 our Agni. These senses and their evolution belong 

 to the upward arc. Coming downwards, Ishvara 

 only gives the power to matter to respond to these 

 particular vibrations, and these vibrations are con- 

 nected on the physical plane with the sub-divisions 

 that I have just mentioned, the different sub-divi- 

 sions of matter, solid, liquid, gas, and so on, 

 corresponding in the sense-organs to the senses. 



Coming downwards, beginning on the mental 

 plane with Intelligence missing the two higher 

 ones of Existence and L,ove He sends out vibra- 

 tions to make the matter of the mental plane 

 answer, aud the vibrations with which that matter 

 answers, that is, a certain range of vibrations, are 

 called mental or intelligent. You may say, Why ? 

 Just for the same reason that in Sir William Crookes* 

 tables definite names are given to the different 

 classes of vibrations, which produce sound, light, 

 etc., names are given in order to express a certain 

 limit of vibratory force ; within one set of limits the 

 vibrations affect the ether, give " light," and the 

 eye receives them. Similarly, vibrations that fall 

 between certain limits of vibratory frequency affect 

 the matter of the third plane, and when they are
