Arthashastra
सैन्यम् अनेकम् अनेकस्थम् उक्तम् अनुक्तं वा विलोप अर्थं यद् उत्तिष्ठति तद् औत्साहिकं अभक्त वेतनं विलोप विष्टि प्रताप करं भेद्यं परेषाम्, अभेद्यं तुल्य देश जाति शिल्प प्रायं संहतं महत् ॥
That army which is vast and is composed of various kinds of men and is so enthusiastic as to rise even without provision and wages for plunder when told or untold; that which is capable of applying its own remedies against unfavourable rains; that which can be disbanded and which is invincible for enemies; and that, of which all the men are of the same country, same caste, and same training, is (to be considered as) a compact body of vast power.
