The Tripurantaka Mantra is a powerful invocation of Lord Shiva in his aspect as the destroyer of the three demonic cities (Tripura). This narrative is primarily found in the Shiva Purana (Rudra Samhita, Yuddha Khanda) and the Skanda Purana (Maheshvara Khanda), which describe how the asuras Taraksha, Kamalaksha, and Vidyunmali built three flying cities of iron, silver, and gold, respectively, and terrorized the worlds. When the gods could not defeat them, Shiva agreed to destroy the three cities with a single arrow from his Pinaka bow. The mantra is chanted to invoke Shiva's power to annihilate negative forces, both external and internal.
The three cities symbolize the three gunas (sattva, rajas, tamas) that bind the soul to samsara, as well as the threefold impurities of ego (ahamkara), karma, and maya (illusion). According to the Tripurantaka Mahatmya, a section of the Skanda Purana, the destruction of Tripura represents the dissolution of the threefold world of subject, object, and experience, leading to liberation (moksha). The mantra is often recited as 'Om Tripurantakaya Namah' or 'Om Hram Hrim Hraum Tripurantakaya Namah', incorporating the beejas (seed syllables) that represent the three cities themselves. The phoneme 'Tra' in Tripura is associated with the threefold fire of desire, action, and knowledge.
Traditionally, this mantra is chanted during Maha Shivaratri and Tripuri Purnima (the full moon day in Kartika), when the destruction of Tripura is commemorated. It is recommended to chant 108 times daily, preferably in the morning after bathing, facing east or north. The mantra is considered fierce and should be chanted with proper intention and guidance, as it can uproot deep-seated karmic patterns. It is also used in protective rituals (kavacha) and for overcoming obstacles, enemies, and diseases.
The Devi Mahatmya (Chapter 12) also alludes to the Tripura theme in the context of the goddess's power. Chanting this mantra with devotion is believed to grant fearlessness, spiritual strength, and ultimately, liberation from the cycle of birth and death.

The mantra may incorporate seed syllables 'Hrāṃ Hrīṃ Hrauṃ' representing the three cities, but the simple form lacks explicit beejas.
