The conception of the five elements, which the mystics have held in all times, cannot be explained in scientific terms, because the mystics have their peculiar meaning. Although it may be called water, fire, air, earth, it must not be taken as such; its nature and character, according to the mystics, is different, but as words are few, we cannot give different names to these elements, although in Sanskrit we have different words for these elements. And so 'ether' is not ether as the scientists mean it. It is capacity. Water is not water as we understand in everyday language; it is liquidity. Fire is understood differently, it means glow or heat or dryness or radiance, all that is living. All of these words suggest something more than we mean by earth, fire, water, etc.
