While unarguably we know even if you have vast richness, on death you can’t carry even a needle with you. It is a universal fact. However, it is believed that the deceased may carry with them the Yangcha, wealth auspiciousness. If so than it will lead poverty to the surviving family.
To counter this, there is a post death ritual, which is known as Yangcha ritual, which means adoration to retain back the prosperity of the family. “Yang” means wealth auspiciousness and “Cha” means wipe.
This brief ritual is performed before carrying away the dead body to the cremation ground. Otherwise as said the prosperity or yang of the house may go away with the deceased person.
Before body is taken out, some jewelry is tied in a piece of the Khadhar (white scarf) and is placed near the dead body. An arrow with five different coloured pieces of cloth, representing five essential elements of nature (Earth, Fire, Water, Air and Space) are tied to it and placed nearby.
When the body is brought out, the bundle of the cloth containing jewelry too is brought out along with it. Then before the start of the funeral procession the lama takes it out from the body with the recitation of prayer and hands it over to such a boy whose parents are alive, termed as phama chai. He takes it inside the house and hands it over to the head of the family.
It is believed that with this all the virtuous qualities of the departed soul and the prosperity of the household is retained there.
I have personally done with my late father.
So please see that it is done and yang of the house is retained back.
