Through the application of embalming , which allows the deceased to be presented in the best possible condition, with a natural colour and the absence of odour or other unpleasant changes which would otherwise follow soon after death.
Modern embalming ensures that relatives and friends who view a person have a memory of one who is peacefully asleep. This is a consolation indeed.
Embalming is necessary if the body is to be kept more than 24 hours, as well as for long distance transportation. Most airlines insist upon a certificate attesting to the hygienic condition for journeys by air.
