A Puranic tale tells of Parasurama having beheaded his mother at the behest of his father. The sage was advised by rishis to locate the temple and to worship the lingam as a penance.
After much searching, Parasurama found the temple in the middle of the forest, dug a pond nearby and began his purgation.
A single divine flower used to grow miraculously in the pond each day, which the sage offered to Shiva as worship.
He appointed a yaksha, Chitrasena, to guard the flower from wild beasts. Parasurama used to bring one hunted creature and toddy everyday for the yaksha.
One day, Chitrasena, a devotee of Brahma, felt tempted to worship Shiva himself. An enraged Parasurama attacked Chitrasena when he found the flower missing.
The battle lasted for 14 years, and was so fierce that a pallam, or pit, was created at the site. ’Gudipallam’, or ‘temple in the pit’, became Gudimallam over time.
Unable to choose the victor, Shiva is finally said to have merged both into Himself, and the figures still etched show the hunted beast and toddy pot in Parasurama’s hand.
Brahma as Chitrasena, Vishnu as Parasurama and Shiva as the lingam form this unique, unparalleled icon.
Further, he blessed them by merging them with the lingam, Brahma crouching down as the dwarf and Vishnu as Parasurama on his shoulders, holding his axe and a ram’s head. Such is the story of this unique temple!
There is an atmosphere of spirituality which pervades this temple, even in the absence of priests or devotees.
After the crowd at Tirumala, a visit to this temple can be an uplifting spiritual experience!
Buses are available from Tirupati Bus Stand, however, there are only a few buses travelling on this route.
HOW OLD IS THIS TEMPLE
According to wikipedia, it has been dated to the 2nd/1st century BC, or the 3rd century BC, or much later, to the 2nd century AD, 3-4th century AD, or even, according to one source, as late as the 7th century AD.
However, since this Lingam is related to Parashurama, is must be of Treta Yuga.
Wikipedia writes, this is "the only sculpture of any importance" to survive from ancient South India before sculpture made under the Pallava dynasty from the 7th century AD onwards, and "its mysteriousness lies in the total absence so far of any object in an even remotely similar manner within many hundreds of miles, and indeed anywhere in South India". If assigned an early date, the figure on the linga is "one of the earliest surviving and unequivocal images of the god Shiva".
The temple is later than the linga; again, estimates of the date of the temple vary considerably, but it is usually dated to "the later Chola and Vijayanagara periods", so possibly a thousand years later than the sculpture. The linga was originally sited in the open air, with the rectangular stone surround that still remains.
The temple remains in worship, but has been protected by the Archaeological Survey of India (ASI) since 1954. (With inputs from megalithic. co. uk and TOI on May 04, 2015).
