The most significant fact about the mention of the Kamboja people in the early literary and epigraphic records of India is that they are usually associated with the Yavanas and often with both the Yavanas and Gandharas.
Denying this claim, the Buddha tells Assalayana how in Yona and Kamboja and other outlying regions there are two vannas, the master and the slave, and that it is possible for a master to become a slave or for a slave to become a master.
