“The whole physical creation is perishable. These material bodies are composed of atoms; when these atoms begin to separate decomposition sets in, then comes what we call death. This composition of atoms, which constitutes the body or mortal element of any created being, is temporary. When the power of attraction, which holds these atoms together, is withdrawn, the body, as such, ceases to exist.“
