All hold and teach that the spirit, when it leaves the body, flies away from _mortality_ and Earth, and goes to the place prepared for it by its Creator. The celerity with which spirit moves we do not now know, but the reality and law of its flight does exist, and this by God's own arrangement and established agency in Nature. That such agency is continually with us, and ready at all times for the use of disembodied spirit, we cannot doubt--nay, possibly its principle or element is _in_ and _of_ us, from the first moment of our existence, through all subsequent time, and will continue to all eternity to come. The _blood_ is the life of man, its element or stimulæ of life is _electricity_, let this but escape from the blood, and with it the soul or spirit has fled, and the body is left to moulder back to dust. We find electricity to be a principle of _immateriality_; an element of _fire_, which pervades all things, in a greater or less degree, not only solids and fluids, but also atmosphere or air. Now let us consider this element which God has permitted man to comprehend as existing in nature, and yet veils it from our sight, and, although he permits us to use it for beneficial purposes, yet we can never see or comprehend more than its _effects_, for, in itself, it is _ethereal_ and no mortal eye can behold it. Man has not only been permitted to comprehend that the principle of electricity does exist in Nature, but also to measure, by time, its rapid flight. Thus, with proper appliances, this Earth can be belted with it in about _one tenth_ part of a second of time. It would seem to almost annihilate time, and space, as its flight is nearly 300,000 miles a second--being more than one third swifter than _light_. In preceding pages, we have dwelt upon the distance of our Earth from the Sun, and also distances to various planets, and to some of the fixed stars, and _nebulæ_, far away in sidereal regions. We have given you the conclusions of the most scientific Astronomers throughout the world. Their measurement of distances by light have been shown to approximate correctness, and the truth of their deductions we cannot doubt. They have explored regions so far remote, that it is rendered certain that it has required _light several hundred thousand years_ from the time it left its native Sun, to reach our Earth, and that these rays travelling from thence, are now successively arriving and beaming upon the eye when it is placed to the telescope. Indeed, from one cluster of suns, or nebulæ, beyond the "milky way," it is computed that the light derived from thence has been 700,000 years in transit, although travelling at the rate of 192,000 miles a second.
