The Vajrasana (IAST: vajrāsana; diamond throne), or Enlightenment Throne of the Buddha, is an ancient stone slab located under the Bodhi tree, directly beside the Mahabodhi Temple at Bodh Gaya. The slab is thought to have been placed at Bodhgayā by emperor Ashoka of the Maurya Empire between 250-233 BCE, at the spot where the Buddha meditated. The vajrasana is the bodhimanda (bodhimaṇḍa; seat or platform of enlightenment) of Gautama Buddha. Being the site where Gautama Buddha achieved liberation, Tibetan texts also use the term vajrasana to refer to Bodh Gaya itself.
