परावापात्प्रत्यावापाच्च चतुर्गुणादाष्टगुणादिति वा विभवतः सैन्यानामावापः ॥ कZ_१०.५.२९ ॥
parāvāpāt pratyāvāpāc ca caturguṇād āṣṭaguṇād iti vā vibhavataḥ sainyānām āvāpaḥ
parāvāpa と pratyāvāpa に基づき、兵力の配分は資源/能力に応じて四倍から八倍とする。
A standardized scaling rule: force allocation should expand within a defined band (4–8×) depending on available resources and the operational method (parāvāpa/pratyāvāpa).
Kautilya anchors military ambition to fiscal and logistical capacity, preventing overextension.
