At the outset, it is important to put on record the epistemological root of the reading of Chanakya’s Arthashastra applicable to this commentary. The main text is from the translated volume by L.N. Rangarajan, titled Kautilya: The Arthashastra published by Penguin in 1992. Rangarajan has himself stated that he was guided by two versions of the original treatise of R. Samasastry and R.P. Kangle.

It may be stated at the outset that this essay is essentially an attempt to identify some critical commonalities in the approaches of Sun Zi and Kautilya, the two profound strategists of the ancient Orient, one belonging to China and the other to India, and who exercised considerable influence for centuries that followed in their respective countries.

Ancient Indian political thought as given in the niti (moral law) lays down that matsya nyaya (big fish swallowing the smaller fish), which is a law of nature, must be eradicated. However, in spite of best intentions it continues to prevail in internal and international politics. Society is bound together by dharma (justice), which is the great protecting principle, and economic prosperity, moral welfare and cultural advancements are the functions of justice.

The community of scholars needs to study Kautilya's Arthasastra and apply his concepts to political theory and other fields of enquiry, such as intelligence, internal security, war, foreign policy, sociology, political psychology, law, accounting and management. In the past, scholars had to memorise the sutras. This may not be possible now given the declining knowledge of Sanskrit. However, this is no longer a hindrance. The first ever English translation of the text was carried out by Shamasastry, but there are now other English translations of the Arthasastra such as that by R.P.
