Science regards man as an aggregation of atoms temporarily united by a mysterious force called the life-principle. To the materialist the only difference between a living and a dead body is, that in the one case that force is active, in the other latent. When it is extinct or entirely latent, the molecules obey a superior attraction, which draws them asunder and scatters them through space. This dispersion must be death, if it is possible to conceive such a thing as death where the very molecules of the dead body manifest an intense vital energy.
H. P. BlavatskyThe world is not prepared yet to understand the philosophy of Occult Sciences - let them assure themselves first of all that there are beings in an invisible world, whether 'Spirits' of the dead or Elementals; and that there are hidden powers in man, which are capable of making a God of him on earth.
