Matsya Purana — Kailasa
ज्ञात्वा तस्या ह्यभिप्रायं क्रूरं देव्याश्चिकीर्षितम् भित्त्वा विशामि पातालं स्रोतसा गृह्य शंकरम् //
jñātvā tasyā hyabhiprāyaṃ krūraṃ devyāścikīrṣitam bhittvā viśāmi pātālaṃ srotasā gṛhya śaṃkaram //
Knowing her cruel intention and what the goddess meant to do, I will break through and enter Pātāla; and, seizing Śaṅkara in the current, I shall carry him away.
It portrays a crisis-time intervention: during a catastrophic, forceful upheaval (suggestive of pralaya-like conditions), the divine actor penetrates even Pātāla and uses the “current/stream” imagery to rescue and restore order.
By analogy, it models decisive protection: when harm is intended against dependents, one should discern the threat and act promptly and courageously—prioritizing safeguarding life and dharma over hesitation.
No direct Vāstu or ritual procedure is stated; the key motif is “bhittvā” (breaking through), a narrative image of crossing barriers rather than a technical architectural rule.
