Seven major pillar edicts have been found at Lauriya-Araraj, Lauriya Nandangarh, Rampurva, Nigali Sagar, Sarnath, Topra, and Meerut. Ashokan pillars probably signify the axis of the world (axis mundi) that separated heaven and earth.
The Kushanas were also called as Guishuang as mentioned by various Chinese texts. Kushanas were also known as Tocharians and were one of the five tribes of Yueh-Chi or Yuezhi.
