Tirumala Dhruva Bera

Tirumala Dhruva Bera is the name given to the idol of Lord Venkateswara in Tirumala Venkateswara Temple, Andhra Pradesh. Dhruva Bera is the official terminology used for the main deity of a temple with the exact translation being The Immobile image and as the name suggests, the idol is stationary and other idols are used for pujas, sevas that requires the deity's presence outside the garbha griham (sanctum sanctorum). Other terms used for Dhruva Bera include Moolavar or Moola Virat (Main Deity), Achala (Main).

Tirumala Dhruva Bera is considered to be Swayambhu - self-manifested and not created by human. According to Sri Venkatachala Mahatyam, Lord Venkateswara came to reside in this sacred spot to provide blessings to devotees in the Kali Yuga. The idol does not conform to the agamas (rules) for making a deity, thus furthering the belief that the temple's idol is Swayambhu.
