Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
प्रनष्टायां तु मायायां ततो जम्भो महासुरः चकार रूपमतुलं चन्द्रादित्यपथानुगम् विवृत्तवदनो ग्रस्तुम् इयेष सुरपुंगवान् //
pranaṣṭāyāṃ tu māyāyāṃ tato jambho mahāsuraḥ cakāra rūpamatulaṃ candrādityapathānugam vivṛttavadano grastum iyeṣa surapuṃgavān //
But when the māyā was destroyed, Jambha, the great Asura, assumed a matchless form that moved along the path of the Moon and the Sun; with his mouth gaping wide, he sought to swallow the foremost of the gods.
It does not describe Pralaya directly; it uses the motif of māyā being destroyed—signaling the collapse of deceptive power—after which the Asura manifests a vast, cosmic-scale form.
Indirectly, it underscores a key Purāṇic ethic: when deception is removed, raw force and ambition may surface; kings and householders are advised to cultivate discernment (viveka) and protection of dharma against both fraud (māyā) and violence.
No Vāstu or ritual procedure is taught in this verse; its significance is primarily mythic-cosmological imagery (the Sun–Moon path) used to convey the enormity of the Asura’s manifested form.
