It is one of the 108 Shiva temples of Kerala and part of the ancient Dwadasha Shivalayam, stretching from Gokarnam to Kanyakumari.

The temple uniquely represents Shiva in his majestic form seated on Nandi, surrounded by his attendants and family, including Parvati, Veerabhadra, and Bhadrakali. Shiva is depicted with his trident, damaru, serpent Vasuki, crescent moon, and third eye, symbolizing asceticism, power, and protection.
Architecturally, Rajarajeshwara has rare enclosed sanctums for Nandi and Kumbhodara. The temple rituals reflect three main forms of Shiva worship: ascetic devotion, auspicious family worship, and tantric rituals.
This temple is a spiritual treasure that blends rich mythology, unique iconography, and deep religious traditions, attracting devotees and tourists alike.
Three Dimensions of Shiva Worship

Ascetic Worship: Shiva as the supreme renunciate, venerated by ascetics seeking liberation.
Auspicious Worship: Shiva with Shakti and their divine family, symbolizing protection and prosperity.
Tantric Worship: Shiva honored through esoteric tantric rituals involving cremation grounds and spiritual practices.
This layered approach makes Rajarajeshwara Temple a unique spiritual hub that blends devotion, philosophy, and tradition.
