Generally, when we go to a prayer place at the end or same time, we meet our close friends. If we meet a lady she says her husband is cheater and he married different girl and she is alone now. We regret for the same, a person who have done many sins he comes to same prayer we know him. We advise prayer is medicine for all social life. And we request him to continue to remove all his sins.
At the praying place we cannot avoid these kinds of people, same time, we meet also a successful person, he just comes and moves fast from praying place, because he believes in work and he is happy with his business. Still he finds time to pray and comes to pray place.
So only some positive vibration is found and more negative and we meet people wanting many things, that is the reason they are at pray place. So the power of the God is reducing when a sinner is visiting, when a person is requesting something from god, so again team of praying people again pray and do some formalities, in Hinduism there is a method adopted for this kind of negative vibration, they do KUMBA ABISHEKAM to temple. This is only to bring back the power of God to help more people and accept all requests of praying people or devotees.
On connection with above matter, here I am posting kumba abishekam done for sri Partha sarathy temple where I live in Chennai and Triplicane, for this temple is cleaned and decorated grandly and big mantras are displayed and finally public allowed to worship again.
