In the crowded philosophical marketplace of ancient India, where sages debated the nature of the self, the structure of the cosmos, and the path to liberation, few voices rang as provocatively as that of the Charvakas.

Arthashastra provides historical examples of kings who were destroyed by yielding to these vices: Bhoja of Dāṇḍakya from lust, Karāla of Vaideha from anger, Janamejaya from greed, Tālajaṅgha from pride, Aila from intoxication, and the Vṛṣṇis from excessive joy.

Arthashastra emphasizes that these first five categories—the fraudulent disciple, recluse, householder, merchant, and ascetic—constitute the five established institutes of espionage (samsthāḥ).
