The overwhelming majority of Vanniyars of India are Hindu.
Rather than believing in one god, they believe in a multitude of
gods.

Pray that God will raise up prayer teams to break up
the soil through worship and intercession.
Ask the Lord to call people who are willing to go to
India and share Christ with the Bhil.
Ask the Holy Spirit to soften their hearts towards
Christians so that they will be receptive to the Gospel.
