Secular literature is an important source of history because the works provide an account of the governance of the empires. The administration policies and the ways of the kings are laid out in detail. The financial and economic policies and social conditions of the people can too be understood. For example, the Arthashastra and Indika provide details about the Mauryan Empire and the Harshacharita written by Banabhatta is about King Harshavardhana.
