Abhimantrit
Doing "Abhimantrit" is a process in which some food, cooked or uncooked, or money is kept in an utensil with a full pot, small not very big, of water. Then by taking a little water in hand and circling the food or money three times with a short prayer according to the occasion it is offered to whosoever is to be given. Now that food or money is called Abhimantrit and and cannot be consumed by the person who has taken it out. This goes to the person in whose name it is taken out. This process is done for donations too.

Saas (mother of the husband), nanad (sister of the husband) and her husband and their children, devar (husband's younger brother), jeth (husband's elder brother) and his wife and their children - not his son's wife because she can give her Baayana to her, mama/mami and their children, chacha/chachi and their children, bua and phoopha and their children etc.
