Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
आहत्य भेरीं गम्भीरां दैत्यानाहूय सत्वरः तुरगाणां सहस्रेण चक्राष्टकविभूषितम् //
āhatya bherīṃ gambhīrāṃ daityānāhūya satvaraḥ turagāṇāṃ sahasreṇa cakrāṣṭakavibhūṣitam //
Having sounded the deep, resonant war-drum, he swiftly summoned the Daityas, and set forth with an eight-wheeled chariot, accompanied by a thousand horses.
This verse is not about Pralaya; it depicts wartime mobilization—sounding the bherī (war-drum), summoning forces, and moving with a chariot and cavalry.
It reflects a kingly duty in Rajadharma: prompt organization of allies and military resources, signaling readiness through formal summons and martial instruments like the bherī.
The key technical detail is martial/vehicular: the cakrāṣṭaka (eight-wheeled) chariot, a descriptive marker used in Purāṇic iconography and warfare narration rather than Vāstu rules.
