Self Realization?

various of prayers with minimum archanai charge of Rm3-RM5

kavadi offering to the God of charge RM10-RM15

breaking coconut ceremony with devotees own money whereby a mysterious lorry frm somewhere will clear all of it and sell somewhere

goat sacrifice prayers which cost about RM2000-RM3000

madi piccai (begging at temple gate prayers) whereby the entire collection goes to temple

pal kudam (milk pot) to offer milk to god's statue with ticket RM3-RM5

Rituals, worships an offerings such as kavadi, cakuk, pal kudam, rolling around the temple, and ect. ect are to attaint self realization or to pay back to God on their fullfilled request and prayers? Just wondering as the numbers are increasing from years to years. Does God accept all these rituals and fullfilled their prayers? At my place there is a family whereby they do 'sacrifice goat prayer' each year and the ladies in the family carry 'pal kudam' (milk pot) every year, and all the siblings are happily married and the family is very happy with wealth and health, on the other hand there is a family whereby the each member of the family will carry out their duty on every spritual prayers. The sisters will carry 'pal kudam' (milk pot), brothers will carry kavadi, the mother will do 'madi piccai' (begging at temple gate), the grandma will do rolling around temple. But recently one of the brother losses his two hands on an accident at work place, another brother and a sister  divorced, the other two sisters are not married. The mother losses her leg of diabetes and the father died on hear attack. Quite confious of the benefit of the offering and prayers. Any comments?
