In recent years, there have been certain controversies associated with them, where the honorable high court and supreme court of India were found intervening.
e.g. certain vaults of Padmanabhaswamy temple were opened or are waiting to be opened; similarly there are issues with women's entry to the Sabrimala area
It appeared as of that there had to be a reason for such restrictions.
Are there any historical curse involved, which may affect the surrounding areas of these sacred places?
