Shiva Purana
रज्जो सर्पश्शुक्तिकायां च रौप्यं नैरः पूरस्तन्मृगाख्ये मरीचौ ॥ यद्यत्सद्वद्विष्वगेव प्रपञ्चो यस्मिञ्ज्ञाते तम्प्रपद्ये महेशम् ॥ ४४॥
The snake in the rope, (he silver in the oyster shell, the water in the mirage—like that when he is known, the whole world vanishes and Sat alone remains. I resort to that great lord.
