Varṇa-dharma and Rājadharma: Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Outline (वर्णधर्म-राजधर्म-प्रश्नोत्तरम्)
रथा नागा हयाश्रैव पादाताश्वैव पाण्डव | विष्टिनविश्चराश्वैव देशिका इति चाष्टमम्
rathā nāgā hayāś caiva pādātāś caiva pāṇḍava | viṣṭinaviś carāś caiva deśikā iti cāṣṭamam ||
Bhīṣma said: “O Pāṇḍava, these too are counted among the divisions: charioteers, elephant-warriors, horsemen, and foot-soldiers; likewise the viṣṭi (forced laborers/levies), the roaming or irregular troops, and the local guides—this makes the eighth category.”
