animal sacrifice

[avii]

in a mariamman temple in the caribbean in which i am a pujarie (new) we have goats sacrificed in puja , however in our country is is viewed as satanic worship and pundits highly disagree with these acts , but i have seen people who do these pujas ,acheve their desires and there is a pujarie in the temple who becomes "possed" by the devi and talk to pujaries saying that everything was done well and was accepted . my question is , is this the practice in other mariamman temples in tamilnadu or south india ?? the pundits also refuse to accept parad is this also common ??
