Some doubt the Law of Metempsychosis or Reincarnation.
The Law of Conservation of Matter states that Matter or Energy can never be created nor destroyed.
Matter exists in three forms – solid, liquid and gaseous.
Ice (solid ) when heated becomes water. Water when heated becomes vapour, which when cooled, becomes water. In other words, Substance knoweth no destruction. It merely undergoes a transformation into conditions which preexisted in other conditions.
Imagine yourself as ice. Ice had preexisted in other conditions as water. Water had preexisted in other conditions as vapour. It is only logical to assume that we had preexisted in other conditions !
Physical Life, therefore, does not begin to be. It merely enters physical conditions and assumes physical guise.
The Law of Conservation of Matter is in other words, the Law of Conservation of Being, where Being is all in all – Matter, Mind and Life !
