Customary laws concerning issues like birth, marriage, and death ceremonies differ across clans.
In the Murasing clan, a purification ceremony is done seven days after a child's birth.
On the day of purification, a holy rite is performed to a water God, and then a Tulsi-God is worshiped.
Each plate bares a name, written with a lighted wick soaked in mustard oil.
Girls of 18 to 80+ years begin to wear a risa bound around their breasts.
In the presence of the heads of the society, each young man and woman is garlanded and given a new name.
Names are chosen with special suggestion to the prominent traits of individual personalities.
The chief of the organisation is sikla missip, a name given to a young man who is a wise natural leader.
Some convention of the youth organization are: All sikla mung chajak (newly ‘baptized’ young men) must be called by their new name.
In any village with a youth organization, no one must interfere with a young man's visit to a girl.
Matters that cannot be settled through the youth organization are handed over to the village elder-council.
If most of the young people in a village get married, the old organization dissolves and a new one begins.
Many of these conventions are gradually being lost, but they indicate a highly developed social control system backed by voluntary will.
The groom's parents and relatives go to the bride's house with the social leader willing to finalize the matter.
In Murasing clan all villagers and other relatives are invited in any marriage ceremony.
In the day of marriage at first two ayas take water from a river, accompanied by a band.
The next day of marriage ceremony people take some food as blessing to new couple.
After that the body is carried with waying and holy song, and buried or cremated.
At the bottom of a six or seven foot hole, a vertical tomb extends to the west.
The tomb is filled with salt and fenced with bamboo that keeps soil from penetrating.
For the next three, five, or seven days, family members, relatives, and others perform a death ritual.
