The workers that do the duty of taking care of human beings that have come to the end of their existence,namely that nave reached death deserve a praise. They do their work in a very motivated way when they arrange cremations so that they don't display any offensive ,ugly sights.They do their work as if they were the blood-relations or brothers and sisters of the departed.
This is a way of relating to our friends in the human realm that pays respect to the fact that everybody is in the same situation that can't be avoided.To take care of each other in this way is indeed something most praiseworthy.
Ceremonies like this reflect the way we fulfill our duties of support and care for each other.
