वहाँ व्यूह निर्माण करनेके लिये रथ और वाहनोंसे उतरना तथा पैदल सैनिकोंको छिपाकर रखना सम्भव है। वहाँ रहकर शत्रुओंके प्रहारका जवाब दिया जा सकता है और आपत्तिके समय छिप जानेका भी सुभीता रहता है ।।

毗湿摩说道：“在那样的地方，可以下车离辇以布置战阵（vyūha），并能将步兵行迹隐蔽。居于其间，既可回击敌人的打击，危急之时亦便于藏身。让战士们以‘七圣仙’（Saptarishi）为后盾，稳如群山而战。依此阵法与坚守之道，进攻之王仍可望战胜那些本难征服的强敌。”

Educational Q&A
Steadfastness and correct tactical arrangement are presented as dharmic instruments of victory: by placing a revered, stabilizing support at the rear (symbolized by the Saptarshis) and fighting without wavering, even formidable opponents can be overcome.
In Bhishma’s instruction on governance and warfare in the Shanti Parva, he advises a specific battle posture/array: keep the ‘Saptarshis’ behind as a stabilizing rear-support and engage the enemy with mountain-like firmness, thereby increasing the chance of victory against difficult foes.
