A Hindu temple or Mandir is a house of worship for Hindus, followers of Hinduism. They are usually specifically reserved for religious and spiritual activities.
A Hindu temple can be a separate structure or a part of a building. A feature of most temples is the presence of murtis of the Hindu deity to whom the temple is dedicated. They are usually dedicated to one primary deity, called the presiding deity, and other subordinate deities associated with the main deity. However, some temples are dedicated to several deities, and some have symbols instead of a murti.
