| ||Lord Shiva in the temple is Swayambumurthy. Girivalam-cicumambulating the hill takes place on each Poornima-full moon days. The age of the holy tree Vanni is over 1700 years. It is the faith of the devotees that salvation is surety if he/she is born in the place, or live in the place, or pray the Lord here, or even thinking of Him even while elsewhere and die in this place. One of the above five criteria will free him/her from the cycle of births and deaths. As in Kalahasthi temple, Lord Vinayaka is in an underground shrinewith 18 steps to get in for worship. When the world was destroyed by pralaya floods, it is said that this holy place-Vruddhachalam stood unaffected and fully alive. Of the 1008 Shiva shrines of the country considered in high esteem, four lead this divine list of which Vruddhachalam is one. Saiva Siddhantha comprises of 28 Agamas-branches. Lord Muruga installed 28 Shivalingas representing this philosophy and performed pujas. These Lingas are in a separate shrine northwest of the temple. Lord Vinayaka is in the south line of the Lingas and Lord Muruga with His consorts Valli and Deivanai is in the north line. The Shiva Lingas bear the names of the 28 Agamas – Kamikeswarar, Yogeswarar, Sindhyeswarar, Karaneswarar, Ajitheswarar, Deepadheswarar, Sukshmeswarar, Sahasreswarar, Amsumaneswarar, Sapradeswarar, Vijayeswarar, Viswaseswarar, Swayambeswarar, Analeswarar, Veereswarar, Rouravareswarar, Makudeswarar, Vimaleswarar, Chandragnaneswarar, Mukambireswarar, Sarvothameswarar, Parameswarar, Kiraneswarar and Vaduleswarar. |
