As per Hindu thought, any one can pray the God in any form and it reaches the God. those of who want to pray the god, s/he may be of any religion/caste/nationality, should be allowed to have the Darshan in temple. Really the priests of temple are doing the harm to Hindu religion by their act. God himself is "Patit Pawan" and He makes the devotees "Pavitra" and blessed. How come devotees can make a temple "Apavitra" It is simply absurd.
