The most convenient method in which we can arrange the various branches of our subject will perhaps be the following: first, to consider rather caref… - Charles Webster Leadbeater

Long before the discovery of radium led to the recognition of the electron as the common constituent of all the bodies previously described as chemical elements, the minute particles of matter in question had been identified with the cathode rays observed in Sir William Crookes' vacuum tubes. When an electric current is passed through a tube from which the air (or other gas it may contain) has been almost entirely exhausted, a luminous glow pervades the tube manifestly emanating from the cathode or negative pole of the circuit. This effect was studied by Sir William Crookes very profoundly. Among other characteristics it was found that, if a minute windmill was set up in the tube before it was exhausted, the cathode ray caused the vanes to revolve, thus suggesting the idea that they consisted of actual particles driven against the vanes; the ray being thus evidently something more than a mere luminous effect. Here was a mechanical energy to be explained, and at the first glance it seemed difficult to reconcile the facts observed with the idea creeping into favour, that the particles, already invested with the name "electron," were atoms of electricity pure and simple. Electricity was found, or certain eminent physicists thought they had found, that electricity per se had inertia. So the windmills in the Crookes' vacuum tubes were supposed to be moved by the impact of electric atoms.

We have long accepted the doctrine of the evolution of the forms in which dwells the Divine Life; here is the complementary and far greater idea of the evolution of that Life itself, showing that the very reason for that wondrous development of higher and higher forms is that the ever-swelling Life needs them in order to express itself. Forms are born and die, forms grow, decay and break; but the Spirit grows on eternally, ensouling those forms, and developing by means of experience gained in and through them, and as each form has served its turn and is outgrown, it is cast aside that another and better form may take its place.

A great change too will come over the power side of man’s development; the whole question of government and organization will stand upon a different basis. Men will see then vividly and clearly the effect upon the astral plane of many of their actions upon the physical, and thus much that is now done thoughtlessly will become an absolute impossibility There could be no possibility of the slaughter of animals for food, for example, if only men were able to see the results upon the astral plane which that slaughter produces. The crime which men call sport would be utterly abolished if they were able to see what it is that they are really doing. It needs so slight a development to change the whole face of this which we call civilization, and to change it very much for the better. p. 345
