Mantralaya is a town in Kurnool district in Andhra Pradesh, India. Mantralyam is a Hindu religious place where the Moola Brindavanam of Sri Guru Raghavendra Swamy is located. Sri Guru Raghavendra Swamy, (1601-1671), was an influential saint in Hinduism. He advocated Vaishnavism (i.e. worship of Vishnu as the supreme God) and Dvaita philosophy advocated by Sri Madhwacharya. He is considered to be a reincarnation of Prahallada, the devotee who was saved by Vishnu, in his avatar of Narasimha. Shri Raghavendra Swamy is said to have performed many miracles during his lifetime and is believed to continue to bless his devotees to this day and will continue to do so.
Raghavendra Swamy temple, the temple and "Mutt" complex is the main attraction here, but most people here are believers, not sightseers. If you go in the evening on special occasions (of course it is a regular event around 8.00 PM), you can see chariots carrying the deity being drawn around the temple and the temple elephants paying obeisance to the deity. It is quite a spectacular sight. There are three chariots, one plated in gold, the other in silver and the third in sandalwood. Behind the temple the Tungabhadra River flows, which is also worth seeing.
It is a must to wear dhoti for gents and Indian attire like sari, salwar kameez for ladies to enter the sanctum if you want to go near to the Brindavan or do aarthi on your own.
Timings: 6 AM-2PM, 4PM-8PM.
