Why silk clothes had to be worn when visiting a temple

 Nobody was allowed  to go into the temple in old or dirty clothes in olden days; in fact silk clothes had to be worn when visiting a temple, because silk helps in generating body electricity and protecting it, so silk clothes always remain fresh, however much you wear them.

 

It is one of the  precautions and arrangements which made the temple charged, and so anyone also just passing by was affected by the magnetic field of the temple. And when a temple is equipped with them, it becomes charged.
