Oppiliappan Temple in Thanjavur enshrines the unique and auspicious form of Oppiliappan, Vishnu as the deity who married Bhumi Devi (the earth goddess herself). The moolavar depicts Vishnu in his manifestation specifically as the bridegroom of the earth, emphasizing the absolute sanctity of matter and material existence. This manifestation celebrates the principle that creation itself is sacred and worthy of divine love and commitment. The deity's unique presentation honors all material existence through the sacred union with the earth goddess, elevating physical reality to the status of divine beloved. The temple's architecture incorporates distinctive features honoring the sacred union and its cosmic significance. The sanctum maintains an atmosphere celebrating this unique cosmic marriage. Surrounding structures include shrines to Bhumi Devi and spaces for worship acknowledging the divinity present in material creation. The temple's location in Thanjavur, one of South India's most historically important cultural centers, positions it within a geography of extraordinary artistic and spiritual achievement. The unique characteristic of this temple is that its prasad contains no salt, a remarkable feature symbolizing the purity of the union and the sanctity of Oppiliappan's offering. The saltless prasad itself becomes a teaching, emphasizing that true sacred relationship requires absolute purity and the transcendence of all ego-based desires. The deity's love for Bhumi Devi becomes a model for sacred relationship expressing itself through commitment and blessing rather than possession or domination.

The sthala purana of Oppiliappan celebrates the cosmic marriage between Vishnu and Bhumi Devi, the earth goddess herself. According to sacred narratives, Vishnu chose to manifest this particular form to emphasize the absolute sacredness of matter and the material realm. The marriage symbolizes not the pollution of the divine by material contact but rather the elevation of material reality through divine love and commitment. The mythology celebrates the principle that the highest spiritual realization includes, rather than excludes, the blessing and sanctification of material existence. Oppiliappan's marriage to Bhumi Devi demonstrates that true love encompasses and honors the beloved in their complete reality, not just abstract spiritual essence. The cosmic union becomes a teaching about the sanctity of all material creation and the divine's absolute commitment to blessing all dimensions of existence. The unique feature of saltless prasad has profound symbolic significance. Salt, representing desire and taste preferences, is excluded from the offering, emphasizing that this divine relationship transcends personal ego and desire. The tastelessness of the prasad becomes a taste of divine love—the supreme satisfaction arising from communion with sacred truth that transcends all sensory pleasure. Local legends speak of the temple's power to sanctify all aspects of human life and material existence. Pilgrims report experiencing profound spiritual elevation of their ordinary life circumstances through meditation at this temple. The accumulated power of countless generations recognizing the sacredness of material existence has established Oppiliappan as a location where the boundary between sacred and profane dissolves completely.
