Chapter 19: Prativyūha of the Pāṇḍavas — Vajra (Acala) Formation and Dawn Omens
एष व्यूहामि ते व्यूहं राजसत्तम दुर्जयम् अचलं नाम वज्राख्यं विहितं वजपाणिना,“नृपश्रेष्ठी) यह लीजिये, मैं आपके लिये अविचल एवं दुर्जय वज्रव्यूहकी रचना करता हूँ, जिसका आविष्कार वज्रधारी इन्द्रने किया है
sañjaya uvāca | eṣa vyūhāmi te vyūhaṁ rājasattama durjayam | acalaṁ nāma vajrākhyaṁ vihitaṁ vajrapāṇinā ||
サンジャヤは言った。「王の中の最上者よ、いまそなたのために、破り難き陣を布こう。揺るがぬ『アチャラ』、また『ヴァジュラ（金剛）』とも呼ばれる陣であり、雷霆の武器を執るインドラが定めたものだ。」

Educational Q&A
The verse highlights that warfare in the Mahābhārata is governed by structured knowledge (vyūha-vidyā) and disciplined organization, reminding rulers that choosing war entails deliberate, accountable planning—not mere impulse—thereby sharpening the ethical weight of royal decisions.
Sañjaya announces that he will arrange a formidable, ‘immovable’ battle-formation for the king he addresses, specifying that this formation—called Acala and also Vajra—was originally devised by Indra, thus lending it prestige and implying exceptional defensive strength.
