The spiritual pole literally called as kambam should be in the shape of “V” when cutting out from the tree. This action can be done only by the person who planted the tree.
The first step in the process of festive celebration after the announcement of the Ninnu Satru is called as Kambam Poduthal.
Therefore this ceremony is to find the person who is eligible to break the kambam and does pooja before planting it. It is called as kambam naduthal in Tamil.
