The Sri Kalahasti Temple, also known as Srikalahasteeswara Temple, is a renowned Hindu temple dedicated to Lord Shiva. It is located in the town of Srikalahasti in the Tirupati district of Andhra Pradesh, India. Here's a detailed overview of the temple:

Deity and Significance:

The primary deity is Lord Shiva, worshipped as Kalahasteeswara, representing the Vayu Lingam (wind element), one of the Pancha Bhoota Sthalams (five elements).

His consort, Goddess Parvati, is worshipped as Gnanaprasunambika (the giver of knowledge).

The temple is considered "Dakshina Kailasam" (Southern abode of Shiva) and "Kashi of the South" due to its immense religious significance.

It is particularly famous as a Rahu-Ketu Kshetra, where special poojas are performed to mitigate the astrological effects of these celestial bodies.

Legend and History:

The name Srikalahasti is derived from three ardent devotees of Lord Shiva: a spider (Sri), a serpent (Kala), and an elephant (Hasti), who attained Moksha (liberation) for their unwavering devotion. Their stories are depicted within the temple.

Another significant legend is that of Kannappa, a hunter who offered his eyes to stop the bleeding from the Shiva Lingam, demonstrating his extreme devotion.

The inner temple is believed to have been constructed around the 5th century during the Pallava period.

The main structure and outer temple were largely built in the 11th century by the Chola emperor, Rajendra Chola I.

The magnificent Gopurams (entrance towers) were constructed by Kulottunga Chola I during the 11th century.

The Vijayanagara dynasty, particularly King Krishnadevaraya in 1516 AD, also made significant contributions, including the 100-pillared hall.

Architecture:

The temple showcases the Dravidian architectural style, characterized by intricate carvings and sculptures.

It is situated at the base of a hill, with the Swarnamukhi River flowing nearby.

The main entrance faces south, and the sanctum sanctorum faces west.

The Shiva Lingam is made of white stone and is said to be self-manifested (Swayambhu). It has markings representing the spider, serpent, and elephant.

The temple complex has several Mandapams (halls) with intricately carved pillars, including the 100-pillared hall.

There are shrines dedicated to various other deities, including Ganesha, Gnanaprasunambika, and others.

The temple has three main Gopurams, with the main Rajagopuram reaching a height of approximately 120 feet.

Unique Aspects:

Vayu Lingam: The Lingam is worshipped as the embodiment of wind, and devotees can feel subtle movements even when there is no apparent breeze. A lamp inside the sanctum is also said to flicker constantly despite the absence of wind.

Rahu-Ketu Pooja: This temple is renowned for its powerful Rahu-Ketu Pooja, believed to alleviate negative astrological effects.

Eternal Flame: An eternal flame near the Akasha Linga (representing space) is said to burn continuously without external fuel.

Unchanging Structure: Some believe that the temple's structure remains largely unchanged over long periods.

River Swarnamukhi: The river is considered sacred and is believed to cleanse devotees of their sins.

Other Notable Points:

The temple is mentioned in the works of Tamil poets like Nakkeerar and Telugu poets like Dhoorjati, highlighting its ancient significance.

It is one of the Paadal Petra Sthalams, revered in the Tevaram hymns of Saivite saints.

The temple remains open even during solar and lunar eclipses, unlike most other temples.
