When a man dies, his body only dies and not the soul. Just as when a glass bottle is broken, it's shape as a bottle is only altered and not the chemical aspects of glass and the air in the bottle escapes and merge with the air in space.

Just as a lamp lits a house soul keeps body active and alive. Just as sun shines all over the world paramathama (Super Soul) sets all souls in action.

Just as man abandons wornout clothes and wear new ones in its place, Soul leaves withered old aged body and takes young new body. Sometimes it may even leave younger bodies met with accident as man may cast away even new shirts torn by a sharp metal.

Appearance and disappearance of body is quite common and natural and grief over such incidents is utter foolishness.
