The Thillai Nataraja temple enshrines Shiva in his sublime form as Nataraja, whose dance (the Ananda Tandava) sets the rhythm of creation, preservation and dissolution. Its golden-roofed Chit Sabha (hall of consciousness) houses the famous Chidambara Rahasya — the 'secret of Chidambaram' — an empty space behind a garland-hung curtain, representing the formless, all-pervading divine (space/akasha). The temple is administered by the Dikshitars, a hereditary community of priests, and its sculpted halls include depictions of the 108 karanas of classical Bharatanatyam. It is a masterpiece of Chola-era art and Shaiva philosophy.
