राष्ट्रगुप्ति-संग्रहः
Protection of the Realm and Principles of Revenue & Local Administration
भीष्म उवाच राष्ट्रगुप्तिं च ते सम्यग् राष्ट्रस्यैव तु संग्रहम् । हन्त सर्व प्रवक्ष्यामि तत्त्वमेकमना: शृणु
bhīṣma uvāca rāṣṭraguptiṃ ca te samyag rāṣṭrasyaiva tu saṅgraham | hanta sarvaṃ pravakṣyāmi tattvam ekamanāḥ śṛṇu ||
Bhishma said: “I shall explain to you correctly the safeguarding of the kingdom and, indeed, the proper consolidation and maintenance of the state. Come— I will tell you everything, the essential truth of it. Listen with a mind made single-pointed.”
भीष्म उवाच
Bhishma frames kingship as a disciplined science of protecting the realm and holding it together through sound administration; the ruler must learn the 'tattva' (essential principle) and listen with focused attention, implying that state security and welfare are ethical duties within rajadharma.
In the Shanti Parva dialogue, Bhishma begins a structured instruction to the king (Yudhishthira) on how to safeguard and consolidate the kingdom, signaling a transition into detailed counsel on governance, security, and the practical duties of a righteous ruler.
