 It is thought that Ashoka built in Bodh Gaya the Diamond Throne, in order to mark the place where the Buddha reached enlightenment.According to tradition, Ashoka was profoundly grieved when he discovered that the sacred pipal tree was not properly being taken care of and dying out due to the neglect of Queen Tiṣyarakṣitā.As a consequence, Ashoka endeavoured to take care of the Bodhi Tree, and built a temple around it.
