समे व्यूहे देशकालसारयोगात्सिद्धिः ॥ कZ_१०.६.४७ ॥
same vyūhe deśa-kāla-sāra-yogāt siddhiḥ.
Even when the battle-array is evenly matched, success is achieved by correctly integrating (i) terrain, (ii) timing, and (iii) the decisive advantage (the ‘essence’/main strength).
Exploit ‘deśa-kāla-sāra’: choose terrain, timing, and the decisive factor (core strength/advantage) so that equality becomes asymmetry.
The decisive concentration—best troops, key capability, critical supply point, or main effort—applied at the right place and time.
