We do come across a situation where some people go missing and they never return nor they can be traced.
When such missing people failed to appear for many years there is no alternative on the part of the family to assume the person dead and carry out death rituals in absenteeism.
However, a situation also arises where after conduction of Ghewa, the person unexpectedly comes back to home.
What should you do under such circumstances?
Well, as per our tradition, the person should not be allowed to enter house directly. The person has to stay out for some days and need to undergo the reversal rituals to nullify Ghewa performed for the person assumed as death.
Only then the person is allowed to enter the house and merged with the family. Otherwise it is believed that they carry evil spirits and harm the family.
