Man is not dead when he is cold, stiff, pulseless, breathless, and even showing signs of decomposition; he is not dead when buried, nor afterward, until a certain point is reached. That point is, when the vital organs have become so decomposed, that if reanimated, they could not perform their customary functions; when the mainspring and cogs of the machine, so to speak, are so eaten away by rust, that they would snap upon the turning of the key. Until that point is reached, the astral body may be caused, without miracle, to reenter its former tabernacle, either by an effort of its own will, or under the resistless impulse of the will of one who knows the potencies of nature and how to direct them. The spark is not extinguished, but only latent - latent as the fire in the flint, or the heat in the cold iron.
