Pancha Bhoota Stalams — The 5 Element Shiva Temples.

Tamil Nadu

Ekambareshwar — Prithvi (Earth) element. The lingam is made of earth itself; no abhishekam (anointing ritual) is performed because of its composition.

Tamil Nadu

Arunachaleswar — Agni (Fire) element. The 1,055m sacred Arunachala Hill IS the lingam; the Karthigai Deepam beacon lit on its summit in November is visible from 35km.

Tamil Nadu

Nataraja Temple — Akasha (Sky/Ether) element. The empty sanctum behind the curtain is the original 'Chidambara Rahasyam' — the sky-element invisible by definition.

Tamil Nadu

Jambukeshwarar at Tiruvanaikaval (Trichy) — Appu / Jala (Water) element. A natural underground spring keeps the sanctum's sub-shrine permanently flooded.

Kalahasteeswara — Vayu (Air) element. The flickering lamps in the windless sanctum supposedly move on their own, evidence of the air deity's presence.
