Death is a door opening from one aspect of life to another. Death is cessation of bodily or physical activity, of physical and organic function, of physical consciousness. Death is a transition from one state of being to another, a change of the from of consciousness to another plane, astral or mental. Ice becomes water, and water becomes steam, vapour, and invisible gas, according to the degree of vibration. So is life in the physical, astral, and mental planes.
